4 Ways to Eliminate Arc Blow

[@Gerhardter]

I hope I can help you out with my "alpine English"... We'll see. "Arc Blow" is caused by the Lorentz force. A current which is flowing in a certain direction and a magnetic field (which may be induced by the current or a permanent magnet) interact with electrically loaded particles and deflects theyr movement. Basicly, the arc is just a flow of electrons and other electrically loaded particles. "Arc blow" is a situation where the flowing current, the magnetic field and the arc are in a "sweet spot" where the Lorentz force causes a deflection of the arc. If you go ahead and change the direction of current in the workpiece by using two ground clamps or repositioning, or if you change the magnetic field by wrapping the ground lead over the work piece, or if you use AC which alternates the direction of the flowing current in the workpiece, you simply eliminate that "sweet spot". Often, arc blow is also caused my permanent magnets which are too close to the arc. I hope that this makes things a little clearer for you. By the way: The Böhler Fox EV50 is the "go to" 7018 over here in Austria. It was initially developed by Böhler / Voest Alpine and it's a widely known and well recognized electrode. I'm using lots of Böhler electrodes, including the EV50 for structural stuff and the FFB for heat resistant steels, and I can really recommend this brand.

Wow this helped out tremendously! I asked my instructor last night, “How do you control arc blow?” “Arc flow??” “No. Arc BLOW.” “…what do you mean?” 🤦‍♂️

[@WaffleStaffel]

​@@Welddotcom I'm just learning about welding, and just now heard about arc blow. These are some pretty ingenious workarounds. Even though it's just a chunk of metal and not a coil, the huge current running through it is turning it into an electromagnet and pushing the molten metal around with eddy currents and whatnot, as Gerhardter described. The short jumper is ingenious. It "short circuits" the piece and moves the magnetic edge away from the physical edge. I don't know if it's _"Magnetohydrodynamics"_ or just electromagnetism, because supposedly arc blow only applies to ferrous/magnetic materials. kzbin.info/www/bejne/h3LVlIevobOipbM

[@NickFrom1228]

I don't want to get too picky here but we all need to stop saying "Electricity is going to take the path of least resistance." It's a huge safety issue. In reality, we should be saying "Electricity takes every path possible with the amount of current in each path being inversely proportional to its resistance." That way everyone understands that the electricity is taking lots of paths and any number of them may kill you if you are not careful.

[@NickFrom1228]

@Freedom Justice The key here is context. Lightning, super conductors and micro-heating don't really matter in the practical sense. It's a technicality that unnecessarily complicates people's understanding. What people do need to know is that they should not be thinking about a single path of least resistance for current paths related to commercial and residential power. This is a mindset issue that goes beyond welding. It has to do with any current source beyond small batteries. If people will treat current paths in the plural instead of the singular then more people will be alive at the end of the year than not. Additionally, more people will be alive if they think this way than if they understand lightning, super conductors and micro-heating. I don't get into these things because it won't really help people but helping understand that they can be killed from any number of current paths will. I'm not dismissing what you say, I'm just saying it muddies the waters for people's understanding.

[@87mini]

@Freedom Justice You're confusing "intelligence" with "knowledge". Funny that you accuse him of being egotistical, when the tone of your response is that of a lord talking to a fool, not a teacher to student. You make repeated statements about how Kenn "thinks", when you are actually projecting your annoyance at someone having the arrogance to argue. This is the kind of discussion that goes on in talk radio, not among intellectuals, and while you may have a lot of technical intelligence, you really need to work on your emotional and social intelligence if you would like to have constructive relationships with others. Oh, and there is no such thing as "false facts", so "true facts" is a redundant term. Try not to be so combative in your discussions - you can learn far more from polite conversation than aggressive. It sounds like you have a lot of knowledge - but remember that we all come from a state of ignorance, and knowledge can sure that. Intelligence is much more nuanced and complex, and if you despise those who seem less intelligent to you, you will miss many chances to increase your knowledge, and isolate yourself from both the less intelligent, and the intelligent who practice compassion.

[@davidmarquardt2445]

As I understand it when you strike an arc it ionizes the air and creates a plasma. Plasma's are sensitive to magnetic fields, as you are welding your magnetizing the piece, that's why you tend to run into arc blow farther up the weld. With AC any magnetization is canceled out by the reversing polarity ~.

[@claytonhanika1992]

Always weld towards your ground ie vert weld clamp at the top of the piece. Always works for me. The worst arc blow is on a direct moment weld beam to H column on the bottom flange root if you clamp it to the end of the run off tab it cuts down on it but can’t ever seem to get by it

[@nesscole8253]

So the ground would have to be on the bottom of the plate??

[@Tictacpanter]

I wonder if you wrapped part of your electrode line around the workpiece (similar time the last method) if it would disrupt arc blow in a similar fashion. Would be useful in those outside jobs.

[@MrDougMel]

Used to get a lot of arc blow welding multiple gussets into wf beams, right in the inside corner where it is most difficult to grind out. The boss would come out and using my exact setup would make a perfect pass. Would frustrate the heck out of me! A few years later I was doing the same with our next apprentice! Great fun then!

[@Chugwater_Cowboy]

Would any of these tips also work for Wire-feed welders? I've tried everything else and by trial and error I've discovered that different brands of wire will cause more or less problems but I've not been able to eliminate it. All simple enough to try though. Thanks.

[@craig265]

The reason why that works when you wrap it aroundor just put the clamp I'm one piece and then on the other end of that same piece. It keeps the inductance the same. Or it's it's strengthens and stabilizes the inductance so there's no fluctuation in the current.

[@Treeezplz]

Yeah it's always toward the end of the rod. You will be laying down a clean one then all the sudden it starts getting super rough!!

[@wicklash9065]

Well im not wroger, but i did find a longwinded insightful answer to what causes it and whatnot. Hopefully this helps someone There is a difference between thermal arc blow and magnetic arc blow. The first thing you need to is identify which is your case. You've stated it's thermal arc blow, but then you've stated "I've tried turning down the heat and moving the ground clamp w/ no success" That later sentence implies you suspect magnetic arc blow rather than thermal arc blow. I believe the other responses reflect that implication. With that said, let's give a rough definition of the two most common forms in ascending order of probability. Thermal arc blow: As you advance along the plate, the gap between the rod and the surface of the weld pool is ionized. That space becomes more conductive and facilitates transfer of the arc/heat from the rod to the plate. This condition sets up "thermal back blow" as the arc attempts to maintain itself through the ionized hot space rather than the cold space/cold plate. Some level of thermal back blow is not detrimental and effectively unavoidable. However; when you try to run to fast, or without enough heat, you're trying to transfer the arc through a zone of higher resistance with the inherent weld quality issues that evolve from that condition. Magnetic arc blow: MAB is due to magnetic lines of force/eddys in an unbalanced condition. It is also the reason thermal arc blow (TAB) is hard to diagnose. The inherent pushing of the arc due to magnetic lines of force/flux can push the arc away from the ionization zone and into a more resistive area which by default increases the arc blow effect. Going back to what causes MAB when those lines of force get out of balance, they tend to leave every increasing levels of residual magnetism. In effect the situation just makes itself worse the longer it's left unaddressed. After some time, TAB is no longer a concern. Fixing MAB is relatively straightforward in that you either eliminate residual magnetism, and or balance the magnetic flux conditions. You've already received some valuable comments in that regards. Defining the difference between TAB and MAB and in particular, the point in which one begins to amplify the other, that is not so easy. Some additional information; Most articles I've read claim MAB can only be caused by 50 gauss (as determined by gauss's law for magnetism) but the evidence I've personally witnessed and researched defies that common logic in that it does not take into account the lower levels in which < 50 gauss flux lines amplify the inherent effects of TAB without leaving > 50 gauss in residual magnetic flux lines. It also doesn't take into account the materials in question. Nickel in particular is also ferromagnetic with a low curie temperature. That low curie temperature when welding materials high in Ni, causes the magnetic domains to align and snap the moment the metal drops below the curie temp. Unlike Fe which has a high curie point, the lower curie point of Ni effectively gives more time for alignment of the magnetic domain fields. These are just some of the points to be considered. I'll desist on theory at this point. But I do strongly suggest you identify which is your case (TAB or MAB) before proceeding.

[@marioleal4307]

[@3Hose]

All three methods include changing the flow of the electromagnetic field at or near the weld.

[@NOTINTERCEPTER01]

Could you use another cable to attach to the work piece clamp and wrap the other end near the piece you are working on?

[@davidcrumrine1165]

Both ends of your cable that your wrapping around the metal has to either be connected to the ground clamp or one end connected to the ground clamp with the cable wrapped around the metal and the tag end of the cable connected to the work piece. It has to be a completed circuit.

[@NOTINTERCEPTER01]

@@davidcrumrine1165 thanks

[@SkillIssueShynes]

In this video Jason says weld away from your work clamp with 1/8th or less rods, but in the 3G D1.1 video a year ago Jason says to weld towards the work clamp with 1/8" or less electrodes. The Lincoln electric Procedure Handbook of Arc Welding says that the EM fields around the electrode and the work piece are both traveling clockwise, and Magnetic arc blow is caused by a contraction of the magnetic field ahead of the rod, because (traveling left to right) there is a high concentration of magnetic fields on the left side of the rod, which pushes the arc to the other side. The reason we see it happen at the end of the 3G uphill is because EM waves move faster thru steel than they do air. The area where the test plate ends is a barrier between steel and air. That barrier is more likely to cause arc blow because the arc wants to stay in the steel.

[@SkillIssueShynes]

This assumes that electrons follow the path of least resistance. There is less resistance on the side of the electrode that is the direction of travel. Travel left to right, risitance is lower on the right and higher on the left. Systems always seek balance, so the arc wants to travel towards the place that offers balance.

[@SkillIssueShynes]

The same applies to 3G uphill. The EM wave is strengthened by the work clamp (move away from the work clamp and the strongest forces are on the away side) therefore, we weld away from the work clamp in all situations where possible. Uphill, that puts the majority of the EM force on the underside of the rod, pushing what arc blow occurs to the top of the rod rather than the bottom.

[@mdexterc2894]

I bet Wroger Wroger is gonna say that the dual clamp method works because it acts kinda like moving your single clamp closer because copper is that much better at conducting electricity. He'll probably also say that wraping the cord acts like an additional inductor that keeps power moving to your piece even if the machine dips for any reason

[@104littleal6]

Wroger Wroger, why did you change your name to "Marc D"? 😆

[@nathanquinlan2719]

It works because resistance in the cable is less than steel plate. Current takes path of least resistance to ground clamp and if it travels too far to get to clamp blow. This cable provides a 2nd clamp with reduced path. Current goes through closest point.

[@wsteede]

Correct me If I'm wrong but what about attaching a Ferrite Choke to the lead? I know its for high frequency noise but maybe it could assist in this situation?

[@ifell3]

Silly question time!! Can you only have one ground per electrically connected piece of metal per welding machine? I.e, if I was welding on a section of I-beam say 50m long, and my earth clamp was down the bottom end by my rig. Surely if you were to join in on welding halfway up, your machine or mine might be overpowered by the return current? AC or DC?

[@jasonbecker3362]

Nope it’s actually pretty common to have several machines welding on the same building at the same time.

[@ifell3]

@@jasonbecker3362 I was always told to keep the ground as close as possible to the work, I guess sometimes it just can't be helped!

[@jasonbecker3362]

@@ifell3 in an ideal situation yes, but once your pulling 300-400 ft. of cable across the job site, you ground as close to the machine as possible so you only have to pull out just enough lead to get the stinger where you’re going to weld.

[@abpsd73]

Basic electrical theory. Even though all the welders share a common ground (all ground clamps on essentially one piece of steel,) each welder is it's own electrical circuit, and only the current that travels through the electrode will return to the welder through the work connection.

[@ifell3]

@Todd Hoover good call on the bearing!! I suppose the return current on the DC has been nearly all used up melting the electrode, I bet AC may be different then as when it's on the fall of the sine wave the person closest would be the least resistance?

[@GeoffPesos]

I imagine the reason arc blow occurs is because as the work piece heats up the resistance increases which increases the amperage. So like when a wire burns up so to does the welding rod kind of burn up resulting in arc blow. As to why those methods work I'd be interested in finding out.

[@Graham_Wideman]

For a given voltage, if the resistance increases, then the current must decrease

[@GeoffPesos]

@@Graham_Wideman you are right I was thinking E = I × R and confused volts with amps in the equation. To me it would still make sense for the electrode to burn up if the volts increases as I imagine, but being that I'm no expert on the science and only know enough to perform electrical diagnostics I could totally be wrong. I'm just trying to exercise my head muscle

[@benjaminreevie7601]

Does it help which direction you wrap the cable? Because you are really creating a magnetic field. So if you wrap it the other way does it have the same effect or make it worse? Thanks

[@Danny-qp5gl]

I have a question. I do structural, and everything we get on a job is painted shop coat grey, and we usually don't grind it off lol. And im not sure if this is acr blow or what but we keep our rods in the box stored in a tool box in the work truck, polarity is right but yet every so often, when running an 18, the puddle and the weld and the sound of the rod burning sounds like you are running a 6011. And this only happens once in a while just like arc blow. What causes that?

[@sergeyzh2731]

Молодцы!!! Даже без перевода всё понятно. Так держать! Спасибо!!!

[@wim0104]

Wrapping the cord around a steel core will resist fluctuations to the electrical current in that cord; so it helps with keeping a stable puddle, but also makes it easier to lose the arc if you don't stay tight enough.

[@wesleymckenzie7375]

Is this effect worse when you are welding metal that isn't a great conductor like stainless? To me it looks like what's happening is you have a difference in charge across the two pieces you are welding which explains misbehaving arc behaviour. Installing that jumper allows that charge to be equalized much more rapidly (copper being a way better conductor than anything you are ever gonna weld).

[@mattfogarty8144]

Another good thing I was taught that works really well is obviously keep a very tight arc but as you go up and experience arc blow your rod is gonna develop a toenail twist your rod on each toe and it'll get rid of the toenail and reduce the arcblow

[@jamesbrandon8520]

We have that magnetic problem Welding with tig when welding pipe sometimes and it makes the arc go backwards towards the tig torch and wrapping the ground usually works but sometimes you have to reverse the direction of the ground coil but once you have your root in everything is good, kind of crazy

[@centurionhomeinspectionsin2253]

Wrapping the cord creates inductance that makes the field away from the weld pool

[@TheIcyhydra]

doesn't that only work on iron tho?

[@John-kc7ko]

Thats what I was thinking too...like it forms some kind of RF choke.

[@emailuser3869]

Turning the lead around most metals (or even air) will create an inductor; yep iron is the best core for an inductor. The video uses a DC circuit... so inductance isn't a factor, because inductors only resists CHANGES to current. In a DC circuit, an inductor would resist the initial increase in current, then act like a short circuit, once the circuit reaches the top welding current. In any electrical circuit, the electrons will take ALL paths to the pole of opposite polarity. My guess is that this has something to do with the magnetic forces that are created (at right hand angles to the direction of current flow). The clamped wire provides a different path for the current and a different set of magnetic field lines. When the field lines at the arc interact with the field lines from the clamped wire (or the wrapped wire)... the arc performs "normally".

[@Graham_Wideman]

@@emailuser3869 The inductance added by coiling the cable will certainly have an effect on DC welding. It will act to smooth the current. That is to say, if the arc encounters more resistance, the inductance will add to the voltage, "forcing" the arc to increase, and vice versa for arc encountering less resistance. It could be that this current-smoothing action helps make the arc more stable and controllable.

[@emailuser3869]

[@SkillIssueShynes]

The quality of the work clamp is important, as is the point of contact. Use a sturdy ground clamp ( most 240v welders under 500 and pretty much all 120V welders don't come with good work clamps. These should be replaced with a good all brass clamp or aluminum spring clamps with thick and solid brass fittings. The standard jumper cable clamp is not good enough.) And be sure to clean the area thoroughly, removing millscale and buffing out scratch marks.

[@PhillyDee215]

Great info 👍

[@lakeschoolrestorationchann1567]

My thoughts on this based on observations: Electricity will follow more than one “path” to ground. Essentially the plate or work piece becomes a “lake of water” for the electricity to travel through. It comes in funneled through both the stinger wire and the ground wire. When it’s in the plate it doesn’t exactly just make a straight line from one point to the other, it spreads out more like lightening. How wide is spreads depends on the resistance and how much electricity your putting through it. When you add heat of melting metal the resistance of areas will change, which means the flow of electricity will change as well. Any drastic change to the flow of electricity can cause the arc to wander. I have seen arc blow and to me it seemed like the arc wandered quickly to the side causing flux to burn off/fall off the side of the rod. This caused a increase in arcgap, improper shielding gas creation, improper flux melting/deposition, and the extreme heat of the arc would cause the exposed metal of the rod to start “burning up” in a way (much like welding a rod with theflux knocked off). Without a doubt some sort of magnetism could be at play (since magnetism will clearly screw with the arc) but just giving multiple paths to “ground” gives stability and multiple channels to ground. The fact multiple grounds works makes me have a hard time seeing enough of a magnetic field being generated is causing that much of a issue. It could be though. Also remember most stick rods are run DCEP which will be more prone to electricity wandering on the work piece due to how electrons flow through the circuit. On ac it is passing through a cycle of essentially 0volts and then re-establishing electrical flow towards the stinger or away. Any stray electrical flow won’t be established for long or at enough of a magnitude to make much of a difference. Interesting stuff. 👍🏻👍🏻 great video as always

Below the rod these magnetic circles spread free into the metal. Now your arc is essentially a conductor encircled by the magnetic field along its way. Picture yourself the place where arc enters the molten metal... Pushing force at the top will prevail and will direct arc elsewhere but away from where no metal left. In addition to that - there is a return current flow into the work piece from electrode. The direction on that clamp will dictate where the magnetic field will be concentrated more. If the clam is at the bottom- it will concentrate field behind your rod (travel). In fact it will oppose to “no metal left” when the rod is at the top. If the clamp will be at the top then you will have difficulty at the top due to two phenomena overlapping and pushing arc away from where you want arc to be. This is how I understand the issue.

@@AY-cj9kp Ok, the makes sense. Thank you.

[@Treeezplz]

Appreciate this video tho. This one will be very helpful

*That contraption works by lowering the metal resistance!*

[@nathanquinlan2719]

Coiling the cable makes an inductor which would be resisting magnetic field changes and smooth it out so no blow.

7018 is a low hydrogen right? Sometimes you have to find good places for ground, the short jumper is a nice trick 💥💥💥💥💥

[@richardrounce7138]

The cable wrap method moves the magnetic field away from the weld area. Arc blow is random and black magic. The solutions are even more magical.

Oh fly arc Current try to find shorter distance Or magnetic flux create buly arc current ( magnetic distortion)

[@terrysowter4798]

Just a question, doesn't wrapping the cord in a coil cause a magnetic field?

[@secretagent5658]

Yes it does. The magnetic field from the coil apposes the magnetic field created in the steel from the stinger. Therefore making the net magnetic field 0. It is essentially mimicking Alternating Current. It is like taking a magnet and sticking the south pole to a piece of rebar. Then on the other end stick the north pole on it and the steel has no magnetic field. Its net magnetic field is 0. Try it yourself with some rebar. It acts like the very center of a magnet where there is no dominating magnetic field created or induced. You're welcome weld.com. and yes, I'm a scientist and I've studied physics for a very long time and I've even taught an advanced physics class in high school for 180 days. I loved it.

[@Graham_Wideman]

@@secretagent5658 Your description is mistaken. Current generates magnetic flux circumferentially around the current axis. The current in the coil wrapped around the workpiece will create magnetic flux around the wire, with the loops adding up to create flux axially along the workpiece (and if the workpiece forrms a loop, the axial lines of flux will return back to the coil section that way, otherwise they will loop through the air.). In contrast, the welding current through the workpiece will create magnetic flux perpendicular to the current flow. Those two fluxes are in different directions and so will not cancel. I am electrical engineer, so work with actual electricity. And I wouldn't be so quick to jump to conclusions about the phenomena demonstrated in this video, given the high currents, low resistances (which change as the weld progresses) high temperatures which may change the metal's magnetic and electrical properties, and the plasma of the arc.

[@secretagent5658]

@@Graham_Wideman You described the same thing I said but longer. The magnetic fields are induced in opposite directions making it cancel out. To those who don't know physics very well they wouldn't know what you are saying because you explain it in a complicated circle. But I made my explanation direct and simple so anyone can understand it. Explaining things in a complicated manner isn't the best for everyone.

[@Graham_Wideman]

@@secretagent5658 No, I did not say the same as you, and you are still wrong. I pointed out that the two fluxes (one from the arc current through the workpiece, and the other from the coil wrapped around the workpiece) are perpendicular, and hence do NOT cancel each other. You mistakenly believe that the two fluxes are parallel but in opposite directions.

[@secretagent5658]

@@Graham_Wideman What you dont realize is that the current from and to the piece is opposite of the wrapped coil. And by saying they are parallel is saying the same thing I am period. I've met students that are like you. And you are going to be stubborn and blind to it until you get shown it in person. So there's no need to continue arguing here because I can show you and show physical proof besides taking. But for students I've met that are like you they work best with physical proof.

I hate arc blow I always get it in overhead and horizontal when I’m doing a important weld lol so annoying

[@danielkennedy8530]

So if current is going one way on the workpiece, and opposite from the electrode... North to North as your magnet analogy, why does man-cub always get his electrode stuck. 🤣😆🤣😆😆

[@jasonbecker3362]

He doesn’t spray enough arc start on the plate before he welds. 😂

Anyone else ever experience arc blow so bad that the weld arc not only all of a sudden blows to the side at a 90 degree angle but will blow out the side of the rod about an inch from the end??

[@SkillIssueShynes]

I experienced this to a lesser degree in class tonight. 7018, uphill 3G at 9" weldment on 3/8 plate, jointed for BU2-A, 115A, 20% arc force, hot start active but not adjustable. Made it 7"" before I had arc backblow and out the sides. Best I could do was stop running the beads at 6.5" instead if the full 9". It was in class and all practice test situations.

I stil cant for the life of me weld a patch in sheet metal. Im already going way up in thickness, like 10ga so I dont burn through. Guess what. Still burn through. Am at the point where maybe its time to sell my welding machine, all the gear and just accept I am a disabled broken vet. I cant find even a shop to get past the tricky bits. Cant find a freelancer willing to come over and teach me or just do it so I can move on. I cant find anything around NYC for 100 miles. Nobody wants to work, learn or teach. Maybe I should just use rivets or gorilla glue...it seems to be the way of the future...forget previous methods and use "high tech" methods that fall apart in 2 years. Sorry for the rant. Just tired, black blew out again worst that my weld. I feel just as broken as the car Im trying to fix.

I've done 3f mig on invar and it does this same thing. Wont even let you weld the last inch or so of the joint. And also tig on armor steel does this to me. But for the armor I just weld to the middle and then weld from the other end to the middle. Something to do with the end of the joint. Science
