MIG Welding Techniques for Building a Mild Steel Roll Cage

[@mrmidnight32]

When your first weld attempt is on your own role cage 🤣🤣 You saved that guys life.

[@jeffsilence7785]

Finally, you guys had a welder who knew how to weld......it's about time !!!

[@MillerWelders]

cwlewis123 - When using the Push method (or forehand technique), it actually produces lower penetration because the arc force is directed away from the weld puddle. The Pull method (or backhand technique) will typically produce deeper penetration. When MIG welding mild steel you can use either method, but pushing usually offers a better view and enables you to better direct wire into the joint. Here's a great article on mild steel MIG welding that can explain more: www.millerwelds.com/resources/articles/MIG-Welding-The-Basics-for-Mild-Steel/

[@MrBen527]

+Miller Welders You forgot a joint there at 5:31.

[@adampark8341]

Thats what he said

[@markproulx1472]

Nice video; very helpful. One suggestion for improvement: note the voltage and WFS values used in each case and, most importantly, how they deviate from the “auto set” values.

[@drvn1]

I understand your method of turning up the heat to get into the joint better and that is fine. My mothod is to keep the settings untouched and pull back the nozzle exposing the inner tip more allowing me to get further into the joint like your 45 degree example. just be careful not to touch or dip the tip.. Other than the risk of dipping the tip there are no negatives to the method I have mentioned.. Just a tip from a professional fabricator to anyone who may not be so experienced..

[@Lonewolf3165]

What about directing the shielding gas? You lose some of that without the nozzle don’t you? Wouldn’t that hurt penetration some? Seriously asking.

[@tylersadden2492]

Good video Chris, I like your technique. Best thing about welding is every welder has their own unique way to generally get the same result, a quality weld is what we are looking for. You should make another video showing how to finish welding a roll cage in its final position.

[@suleshangodoyin]

As a Welderman,I Like the shows,thanks. It's me, Sule

[@skillcollector397]

Greetings, Welderman!

[@martinwilliams9285]

Your right about welding thinner tubing, at my job I'm weld pretty much 12 gauge above or below that, of course it's on a lot of farm or rodeo equipment but learning the proper procedures of how hot you should run it to get penetration, this first welding job taught me a lot and hoping to move up to another welding job to make good money, and maybe open up a shop like this to build roll cages or various projects

[@moparmuscle71]

I didn't realize vertical down was acceptable for a certified cage. I did all mine vertical up like a Boss!

[@Skillgannon83]

great tips, just learning to weld roll cages atm and this is really helpful!

[@justnotdeadyet007]

Why is the completed cage missing weld?

[@gordondavis3492]

Miller Welder, thank you for your input, I agree with you on the push/pull statements you made HOWEVER, that DOES NOT apply to VERTICAL DOWN WELDING like shown in the PIPE/TUBE welding shown in the video I commented on; but flat, of course it's true.

[@jasonparker333]

Hi, I am a hobbyist welder and I was getting holes in thin metal, now I know why, thank you so much for the little tip in your video

[@iknowsstuff]

even a potato could weld better than the first two samples!!

[@myronjohnson8899]

Excellent video. I want to start using some of these techniques with my everlast welder now. Great tips.

[@jeffh7663]

In response to some of the comments, I have welded both in the field on oil sell sites and on roll cages and had them cut apart. It is ok to weld downhill on a cage because you will get the needed penetration and after the main bars are installed, you have to be a contortionist to install the rest of it, only giving the option of welding downhill many times.

[@ggonzalez3181]

you are the best👍😎 I'm learning and thank for this video👍😎

[@alfredmartinez8747]

Excellent video. I learned a lot.

[@MillerWelders]

+alfred Martinez We're happy to hear that. Weld on...

[@Russell218]

Damn, look at those arcs... this guy's a champ. He never even touched-on the hardest part about welding tubing; making smooth arcs. Pulling a weld around a tight circumference like that is annoyingly difficult. You're basically welding blind. That's why most MIG'd cages have more of a diamond shape to the welds, rather than a circle. Even on 3" exhaust tubing, it's difficult to go all the way around without welding off into the sunset somewhere.

[@charlesrutherford4785]

Great video! Noticed that you have a really nice lack of splatter going on and I was wondering how you control that? I can do some good welding with good penetration but it looks like a ball-bearing factory afterwards. I also normally use 75/25 Argon-Co2 and what flow rate do you use and why would you increase or decrease it? Thanks!

[@MillerWelders]

+Charles Rutherford Thanks for reaching out. We're glad to hear you liked the video! There are two main keys to reducing spatter: 1. Proper voltage and wire feed settings - too much voltage will product larger "globular" spatter balls, while too much WFS will cause the wire to buck which will also result in spatter. 2. Contact tip to work distance and torch angle - it is very important to maintain a constant contact tip to work distance (for this application, typically 3/8") and maintaining a constant torch angle. This is very critical and difficult to do as you manipulate the welding gun around the tubing. With a little practice, it will become second nature. You are also using the same gas as the one used in the video. Flow rates are usually set at 25-30 cfh. We hope this helps. Please let us know if you have any further questions.

[@bgd73]

pretty welds are for guys who have perms. when is this faking chunk of iron gonna end. I like the middle welds the best in the examples of what was cut out. Its beautiful. I cried.

[@ricardokliwoodclimaco3098]

Very good - thank you for posting

[@andrewelm3224]

Every thing looked great but what I wanted to see more was direction, how welder moves his arms and wrists from the top to bottom around the tube which is the hard part for me to do, making it look smooth.

[@ruffhed2906]

My eyes are burning...LOL Wow it was a Good weld tutorial.

[@ninja63639]

Are you using lower case E or forward backward motion? Does it make a difference either way?

[@LukaZloglea]

Nice video, tnx for the upload!

[@rockdawg1467]

thanks for showing how to do it right i never knew about push and pull this is the first time ive' seen this in all my years welding

[@LightGesture]

He's still going downhill. If he wanted better quality welds, he'd go uphill with a perpendicular or slight push angle depending on where you are on the pipe.

[@rockdawg1467]

For me this is new also ive been a welder all my life from what i gather pushing a weld is better than pulling because you let less chance of contamination into the weld its self it all depends on argon pressure and if your using flux core wire and the cleaness of the weld material also i heard and i use this on my own mig that using wire cleaner pad and lube pad from cyber weld does keep the wire going to the gun clean and properly lubed for better welds they are not expensive and you can buy a 6 pack three red and three black i use them on my miller 140 mig...and how good the argon/c02 mix is and you have to adjust the pressure up or down 15-25 to see what works

[@MrYosmitty]

rock dawg contamination doesn't come from pushing or pulling in MIG

[@masfabz]

Is a millermatic 180 auto set welder good enough to penetrate and weld this dom material?

[@FCAutos]

Good video!

[@patrickbradford6223]

@MillerWelds - The presenter covered the need for change in settings for the tighter corners, but did not say what the changes were. Also noting the base metal thickness, amps, feed rate etc would be good to add.

[@MillerWelders]

Hi Patrick, thanks for reaching out. Please reference the video at 4:15-4:40 for what the changes are. We typically don't speak to these settings because everyone welds at a different travel speed, has a different torch angle, uses different techniques, etc. Please let us know if you have any further questions.

[@brianb5779]

Sorry but one more question, could you give the wfs,voltage and size wire settings that you used please. Thank you

[@timmytimmy1152]

0.035 duel shield flux cored and run it up the hill,vertical down is as strong as bronze brazing

[@dorsetengineering]

Downhill short-circuit mig has a place, and welding cages isn't it. IMHO...

[@bkpickell]

The funny thing is that they don't want you to stop your welds either. They want a continuous weld. Kind of impossible to do vertical up all the way around without stopping. fyi I'm being half way sarcastic.

[@sharondominguez6687]

Question: You said pulling is a good method on pipe. I build industrial ladders using 2" mild steel w/ Mig can I also drag around the tubing will I get better pen ?

[@MillerWelders]

Pushing usually produces lower penetration and a wider, flatter bead because the arc force is directed away from the weld puddle. In addition, pushing usually offers a better view and enables you to better direct wire into the joint. Dragging typically produces deeper penetration and a narrower bead with more buildup.

[@victormorelo666]

you really inspires !! not sure if you mentioned the amp that you selected to weld those pipes? thank you !!

[@MillerWelders]

+victormorelo666 Thank you for your question. The amperage is determined by the Voltage setting and Wire speed. With the Millermatic 212, there is no volt meter or wire speed meter to tell us the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed. For more information, you can also reference our MIG Calculator on our website: www.millerwelds.com/resources/weld-setting-calculators/mig-solid-core-welding-calculator Please let us know if you have any further questions. Thank you.

[@luckernml25]

Very good welding.

[@josephwillett7283]

I keep seeing a lot of talk about vertical down and vertical up welding, push or pull. Some people question if its good or bad? In the end the answer is.....yes. Anyone can set parameters for a vertical up weld and set them wrong. Yes, one position gives more penetration given the direction of travel blah blah blah. Its a well know fact to all of us that weld for a living. Now, I'm a Welding Engineering Technology major right now and one of the biggest things that our studies have found is that a big part of penetration lies in the work/travel angle. We have found a lot of tests that support the vitality of your need for penetration lies in your parameters (easy enough to figure out) and your work/travel angle. I'm still not sure why this is. I believe that GMAW is becoming such a fast solidification process that lack of penetration/fusion or even partial fusion can be solved by some angle adjustments. Just some food for thought. Not saying I'm right or wrong. Just wanted to let some people know so maybe they could try it and see if it helps somewhere down the line. Cheers!

Muy buen video y buen aprendizage.muchas gracias por existir

[@brianb5779]

I was hoping you could answer this, is this technique of goin forward and then back before goin forward again somethin you have found to work good for cages or is this just how you typically weld. Ive seen and done alot of techniques and do this w tig sometimes but never tried it w mig. Your welds look great and was very curious to see the forward then back. Was hopin u could give some insight on that technique. Thanks and love the video ill be tryin it

[@MillerWelders]

Brian B The torch manipulation used here was mainly for aesthetics. Torch manipulation works very well when filling any type of gap. As the torch moves forward out of the puddle, it causes a freeze line in the back. As the torch is manipulated back into the puddle, there is increased penetration into the base material. Overall, the strongest weld bead is a steady stringer bead, but most people like the aesthetic freeze lines that torch manipulation leaves behind. Also, the technique used in this video was a circular technique. Please let us know if you have any further questions.

[@tomthompson7400]

+Brandon Spence you think ....

[@googleuser5482]

IIRC downhill is ok for up to 1/4" or non structural

[@everardogonzalez5778]

tom thompson I agree but this is just short circuit mig and Brandon the machines they use are different when it comes to pipe it's either stick or dual shield and you drag not push

[@valveman12]

For some tubing joints I find I have to stop and start again because of a poor position. Any tips on proper restart?

[@MillerWelders]

valveman12, Starting and stopping on roll cage tubing is very common. Normally with thicker tubing, starting and stopping is always a point of possible failure due to the colder starting point. With stock car chassis, most of the tubing thickness is .120 wall, making cold starting less of an issue. Also, the massive amount of tubing and triangulation in chassis design overcompensates for any individual stressed applied to one select weld starting point. If you are concerned about starts and want to make sure you are at a higher weld temperature when you hit the weld joint, start (partially) on the stop point of the previous weld, then roll into the joint. Another way to help ensure that your starts are quicker is by clipping off the ball that forms on the weld wire after you finish the previous weld, prior to starting the next. Keep in mind that if you change your weld position and travel from a pull to a push, or vice-versa, the weld will look noticeably different. It takes a slight machine adjustment to go from pull to push and keep the weld appearance and penetration similar. Please let us know if you have any further questions.

[@valveman12]

Miller Welders Than you for the reply and info.

[@jockellis]

What voltage were using for this when not in the 45 degree Vee and what voltage when you were? That steel you used? Is it SCCA approved and how much do you think that Camaro’s cage weighed.

[@MillerWelders]

Thanks for reaching out. With the Millermatic 212, there is no volt meter or wire speed meter to show the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed.

[@sharondominguez6687]

Where you stitching while you were doing the pull method ?

[@MillerWelders]

We are using a couple different “stitching” techniques. Sometimes we do “small circles” and sometimes, a slight “back and forth” motion. These welds could also be done without a “stitching” technique by running in a straight line.

[@jimstools3937]

[@MillerWelders]

+James Weissbach Thank you for your questions. First, we recommend that you take caution with roll cages because someone’s life may be in the balance of your welds someday. We recommend a 240v power source for welding roll cages. It will ensure you have plenty of power to make a sound weld. We hope this helps. Let us know if you have any further questions.

[@milfs310]

What pattern technique were you using? I couldn't really tell just curious.

[@MillerWelders]

This video was developed to illustrate a weld - the specific welding techniques and weld settings used are not necessarily the best for all applications. The Specification Sheet from the manufacturer of the filler metal you use is the best tool to determine your starting welding parameters. We intentionally left the weld settings out of this video because following any local, state, national codes or standards is the responsibility of the welding organization producing the weldment. Testing the weldment will ensure that the settings, technique, and overall procedure that you develop will meet the requirements of any applicable codes or standards. Please let us know if you have any further questions. Thank you!

If i gonna be welding with stick welding machine what electrodes should I use? and what amperage for the 30 and 45 degrees ?

[@MillerWelders]

+toolman talal Thanks for your question. We would recommend using a MIG process to weld in this application. However, if that's not possible, you'll want to use a 3/32" size 7018 electrode. This is a good electrode for welding in all positions, so will work well to handle tubing. To weld with this size electrode, you will need between 65 and 100 amps, depending on how thick the tubing is. For heavier frame rails or tubing (1/8" or higher), you can increase the electrode size to 1/8" and use a 110- to 160-amp machine. Good luck - let us know how it goes!

[@mtrltoolman]

Miller Welders thanks this was an excellent answer :) .

[@carmenalfaro9584]

What setting?

[@jwright650]

reason for having to turn up the machine when you have the longer CTWD is that the amount of stickout effects the voltage.

[@coronaismael9024]

Quick question regarding amps and wire speed I’ve google amps and wire speed charts and in one miller chart it says when using .30 mig wire size the speed is 2 ipm per amp and i just downloaded the Miller app and in there it says 2 ipm per amp when using .35 wire size im a bit confused now with your experience which wire will it be easier to control the wire speed? In which wire size do you usually go 2 ipm per amp or roughly close to 2ipm?

[@MillerWelders]

Hi Corona, thanks for the question. What machine are you referring to in particular? The majority of our small MIG welding units don’t show the welding amperage. Our machines show a 10-100 scale, which is going to be a percentage of the wire speed that a particular machine is capable of running. Thank you.

[@coronaismael9024]

Miller Welders I didn’t make my self clear i apologize for that! I meant to say that in most welding charts i found in google they say that roughly 2 ipm per amo when using .030 mig wire and in the miller app it says 2 ipm when using .035 mig wire, my questions is in which mig wire are size are you more likely to go 2 ipm.

monsterink101 It's going to depend on how fast your move or manipulate the MIG gun. A good starting spot would be voltage at 4 and wire speed at 50 for 1/8 material, or voltage at 3 and a wire speed of 45 for your .083-.095 thickness. Hope this helps.

I liked how he used it in the manual mode...because the auto mode sucks! Mine was an out of box failure and had to be sent back for a board replacement. Even after the board replacement the weld stutters at the beginning of each weld, almost impossible to accomplish a decent plug weld on auto body panel thickness'.

[@MillerWelders]

Gary - you may want to check a few things to make sure the Auto-Set function is working properly. You're connected to 208V or 230V power, correct? A good ground is key, so make sure all paint is removed. The Millermatic 212 is a bit more sensitive to stickout lengths, so make sure to shorten up that distance as much as possible. If you've tried these fixes already, you may want to give our service guys a call when you're in front of the machine to talk through some other possibilities. You can call 920-734-9821 and ask for MIG service. Let us know if you have any other questions.

[@gordondavis3492]

Nicely shot video, kinda concerned that Miller (being a welding industry Leader) would have ensured this gentleman "teaching" knew the difference in push and pull MIG welding before doing this video...CWLewis123 and a couple other guys caught it...PUSHING gives you deeper penetration and PULLING gives you less, plus you gotta haul butt in the travel speed. Looks to me like he was welding most pulling down hill cuz it's easier than pushing up hill..Kool looking roll cage though..

[@MillerWelders]

Hi gordon davis - When using the Push method (or forehand technique), it actually produces lower penetration because the arc force is directed away from the weld puddle. The Pull method (or backhand technique) will typically produce deeper penetration. When MIG welding mild steel you can use either method, but pushing usually offers a better view and enables you to better direct wire into the joint. Here's a great article on mild steel MIG welding that can explain more: www.millerwelds.com/resources/articles/MIG-Welding-The-Basics-for-Mild-Steel/

[@MyKamal03]

stop putting going back with your torch in the puddle, each time you do that you stop the penetration in the front of your weld. AND ALSO DON'T WELD DOWN HILL IT HAS NO PENETRATION!!!!

[@drvn1]

Interesting that you say a downward weld has no penetration.. I am a professional fabricator and I build things that are shot at regularly such as reactive targets like Pie racks, dueling trees, IPSC Targets and lots of other odd jobs that require Armor plate and etc.. A lot of times I use a vertical down technique on crucial areas and even though people are shooting thousands and thousands of rounds at the things I build, I have yet for anything to come back that has broken or failed. Proper technique, heat and travel speed are what gets good penetration. Not the direction you travel. As far as push/pull blah blah, I have to do it all and it is more a matter of circumstance and preference than it is strength. We have tested it and I am here to tell you that a vertical down weld can be very strong.. If it can stand up to the vibration and force transferred from the impact of a .50 cal rifle round or .338 Lapua I think it is fine for a roll cage ;).. I am the lead fabricator of Armorgeddonready.com the targets I build are used at competitions as well as training facilities and gun ranges. if they failed, they would not be.. That is all..

drvn1 i believe that down hill can have penetration.On smaller material thicknesses. Bet when you get into heavy plate and structural welds. Or any thing that is under constant pressure or load. You should always run uphill... Down hand has its place. As in fast production and products that are not great loads of pressure. Also is depends on type of filler you are using. That is just my two cents.. .

[@drvn1]

I guess a .308 round at 10 Meters doesn't create any pressure, or the .50 Barrett at 100 Meters.. All the things I build can be found here.. We do pretty much anything you can think of when it comes to armor.. www.armorgeddonready.com Everything you see on this site I built.. Now granted most things are not welded in a vertical down motion but some things are such as the hinges on the Pie rack and the Brackets that hold the paddles on the dueling tree.. .. Thousands of rifle rounds and no weld failures.. Material ranges from 3/8 to 1/2" thickness.. 1/2" is the very hard AR550 used for the High powered rifles.. such as the .50 caliber sniper rifles and etc.. There is also the "Pulse mode" on the Miller 350 that we use that works very well for the thicker materials. Good setting for Pulse with .035 wire is 25, 440.. When welding in the normal MIG setting with 3/8" down to 1/8" material I have found that 18.1, 282 works really well.. Now I will admit that a Verticle down weld is not as strong as a horizontal weld whether it be a push or pull. However I have one question for you.. Would you rather have a not so good welder which in my experience 80% of welders fall in this category do an upward motion or have a really skilled welder do a vertical down? The main factor in my mind would be the welder and not so much the direction :)

What gas is used to welding ?

[@dudakn9252]

75% argon 25% co2 or straight co2

[@Marycielo87]

There is a missing section in the estructure not welded.
