Tig Welding Penetration & Tungsten Electrode Grind Angle

[@rdaugherty52]

Thanks Jody, I went today and bought a diamond wheel $ 10.00 from Harbor Freight a 6 inch grinder some filler rods came home married the diamond wheel to the grinder got some tungsten purple from Air Gas tried out my grinder works great Now after watching your video I understand the grind angles now after 50 years of stick welding I am going to try TIG I was good at gas welding and it looks similar. It looks fun to old to make a career out of it just want to run some beads anyway enough said thanks for showing old timer new stuff.

[@somejimmydude2121]

From a welder of 18 years, these videos are excellent. Thank you.

[@billsmith5166]

TOT sent me over here. First video I've watched. Very well demonstrated, and I'm looking forward to my binge watching. Thanks!

[@d44n19]

hey jody, i am a welding student from rotterdam (NL) and i really want to say thanks for making these videos. it has been really helpful to me especially the tig welding videos. by watching and applying some tips it gave me a diffrent view on welding. Greetings from holland! Daniël

[@hemiram05]

Jodi, you sir are an excellent teacher. Your arch shots have been the best on KZbin for a long time but they are getting to be ridiculously awesome. Thanks for taking the time and sharing your skills with us.

[@MrNextdoorscat]

english 6g welder here sayin this is the best welding channel on youtube, respect and thank you.

[@SKEptic-mg2dd]

I love watching these shows where the demonstrator has equipment that I will never be able to afford. Started with things the Yankee Workshop was able to produce before I started noticing the planers, lathes, miter sets, and biscuit cutters. Now I look at all the settings my little Tig welder doesn't have.

[@dangrove7552]

Jody is into Primeweld tigs as of late. About 1/4 the price of the expensive brands and absolutely capable of the same results.

[@Derrick-lk1zo]

I know you made a very comfortable living working in the aerospace industry but you missed your calling for sure. If I would have had teachers like you in college and high school I would have been a 4.0 student! Brother you have the most informative and captivating educational videos I've ever had the pleasure to view. I'm a 40yr old Maintenance Mechanic at Century Aluminum Smelter of Hawesville KY and I'm definitely learning more from your videos than any class or training the company has sent me to. Keep doing what you do because we love your stuff and thanks for the knowledge it's the best I've ever seen!

[@hiseminencetheholymacdiarmada]

I'm in my 40s, recently retired from the army, and just started a welding class as part of my major. I've been watching your videos as sort of a means of getting a leg up on class. As of this posting, we haven't touched a welder yet, but after watching all these, I am anxious.

[@michaelanglin622]

Well how’d it go, did you get your degree? It’s been 6 years now, are you stacking dimes or laying down chicken scratch??

[@BobSmith-mc7uq]

Of all the welding channels on KZbin...this is the BEST! Class is never over.

[@offgridd]

Although posted 7 years ago, still spot on! Many thanks for sharing and your pleasant way of presenting and yes, only people searching for this information willbe looking at your video's 🙃

[@dave-d]

Excellent video. Thanks Jody. Just getting to grips with TIG and what a voyage of discovery it is! Got my first job as a welder making refuse skips with a 450 amp MIG. Back tracking to stick just to make sure I can stick metal together now. TIG is still something I have yet to get flowing right. Never been a gas welder so in at the deep end it seems. Prep is everything. My main piece of advice to anyone learning to weld would be keep your mask clean! And no back light behind you. Get the light source out in front and you can really see the weld. These vids are so good as you can really see what is happening. Great work.

[@taohawaii]

I think this is one of your best videos to date. Not very different what you normally do but the compare and contrast was perfect. Thank you again!

[@timmwhite9218]

I'm going to be steepening up my grinds now. an additional benefit of this is that when I've ground my tungstens to the fine taper, as they get contaminated and I regrind 'em, they heat up too hot and too quickly/get used up quickly!! Thanks Jody, this'll save me time and money too. : )'

[@mski349]

Sir, I just came across your amazing channel. Your gift for teaching and delivering instructional material is matched only by your humble attitude. Thank you for being the exception on youTube, Look forward to binge watching your channel and all upcoming videos.

[@josstark8124]

Thanks for taking the time to document the various grind angles and penetrations. Proof in the visuals. 🙂

[@luvkountry]

This is a great video for students to see. I suggest that instructors show this one on their overheads while doing their theory class. Thanks for sharing.

[@Travisfromoregon]

Need video !!! Have to start calling you the king of arc shots.

[@bugdozer]

So true. Looked a few older vids from 2012ish and he's really up'd his game since then, great videos. His hair looks better now too!

[@leonardpearlman4017]

He really is! I sometimes see welding videos where they just show a bright light and a bunch of sparks, and you can't see anything, and it makes me frustrated. Jody's videos are helping me to go that last mile. You can have everything in position and set up right, but what is it supposed to look like? I now think vision is the hardest part, constantly fooling around with different glasses and filters and cheaters to see what we see here on the screen. Sometimes it works!

[@fredsmith6160]

You are a wealth of information and a jewel on the Internet. I really want to learn how to tig weld on my everlast welder so I'm learning everything from scratch.

[@michaelcostello6991]

Really interesting to see effect of tungsten grind angle. Basically you can weld ok with any angle almost !! except the very small/pointed grind angle is best for welding thin material. Thank you for wonderful demo. Mike

[@AlexRodriguez-bb5bu]

So much to learn from your channel each and every video. I often need to try what I've watched with my powertig to let it all soak in.

[@ВладНескучный]

глубина провара, заточка --понятно .хоть бы слово понять... Недавно стал просматривать ваш канал . Ваше отношение к присадке ,расплаву понятны мной давно . Многим не нравилось моё отношение . Спасибо за видео канал .С уважением Влад

[@Welder_iron-1987.]

Что ж я английский язык углубленно не изучал)).

[@berntsteinmetz8564]

Hey Jodi, the halo is, where temperature forces the electrones out of the tungsten. the cooler - the later in the taper they come out. And they leave rectangular to the surface. br Bernt

[@dannyhanny1191]

2:01, you really haven't even started yet, and yet I just learned something of what I've seen and had the effect of with my minor Tig experience. Nobody I was working with told me that the sideways grinding of the tungsten would mess up the output like that, but that's exactly what I was working with ... All I had was a table grinder without any guide like you have there, but had I known I certainly would have made the effort to hold the tungsten in a manner to grind it lengthwise.

[@timmwhite9218]

I use an odd tool for sharpening but it works REAL well. Take an old belt sander, put on 80 grit belt (or finer), turn the whole thing upside down, turn it on, lock the 'on' button switch, and center the belt tracking, put the tungsten in a drill chuck (I use 20V lithium ion DeWalt), set that on low speed, use the tail case of the sander as the guide, and wipe the tungsten across the belt w/ very slow turning speed. This grinds the point metal AWAY from the tip, does not leave swirl marks, and it's real quick to do. : )'

[@shitbox7413]

Great demonstration, I learned a lot, thank you! 👍🏻

[@TYMWLTL]

Thank you for sharing your knowledge and wisdom. You prove the old adage: If you want to keep what you have you must give it away.

[@BoostedMonkey4g63]

Now I can see why I have the the problem where the arc wonders, what would be the best grit for grinding wheel? Mine is too rough and it does wonder like in the video. Thank you for the videos.

[@Milton1111]

I am very grateful for what brings us with their classes I hope to take into account what the videos subtitled

[@miltonjunior78]

Are you not welder, but a realy scientist! Im from Brazil and like a lot your videos! Thanks for sharing your knowledge.

[@metzsmayhem6832]

So I was checking into a Welding Engineer program then I got to thinkin', I can just watch Jody's videos and save myself a whole lotta money. Great Video and lovin my Tig Finger.

[@mattgrover3096]

I have really enjoyed and learned plenty from your videos. I watched em all over the years, funny though, I never even owned a welding machine.... Now that I bought one, I'm learning even more the second time through. Thanks Jody.

[@dannyl2598]

Thanks Jody. I am new to Tig welding and you really help to shorten the learning curve. I appreciate you.

[@lukecalls8279]

I loved how scientifically you controlled the variables

[@studioalbertidesign]

Super cool, precise & concise! I'm going to play around with a blunt grind, never tried it (still learning). Thanks for the video!

[@GogebicYooper]

Really nicely controlled experiment. Up to now, I have always MIG welded--Bam! Metal stuck together! However, as a beginning hobby TIG welder, I don't see much distinction between these welds. They appear different by a few hundred thousands in width and penetration. Is the intent of TIG to be that precise or does this experiment show how things might extrapolate in the 'production' TIG process?

[@papahajek5383]

Interesting. I never thought electrode shape affected penetration. Also, the wandering arc was an eye opener. If I was still in the trade I would definitely look into using a finer grinding wheel. I remember holding the electrode so that the grinding lines were parallel with the center rather than across. This usually resulted in grooves in our wheels, but cut down on arc wandering. I wonder if the penetration difference is a result of more electrical resistance at the tip of the sharper electrode.

[@baronburgamot243]

"Here it is again in slow mo because it looks cool" Love your channel man.

[@scottcarr3264]

Jody, Another excellent video, as usual. These demo's are perfect for people still learning (like me). I do use that middle size angle most of the time unless i'm welding Alluminium.

[@vanfather_candm]

Big thanks for making this vid when you did. I'm not sure if I requested this topic or if I was thinking of doing so, but the info comes exactly when I needed it. Thanks again

[@barrettsmith8957]

THESE are the kind of videos I love! Your experience and pragmatism really show!

[@Aint1S]

I'm right there with you on that second grind. CK has some information on dimension vs penetration. Max is 3 times the diameter of your tungsten according to their information. I like 2/3 of the diameter and the tungsten really settles in cleanly on long runs of aluminum. Just the best in my book too.

[@jlstazz]

Something I'd like to see demonstrated is old school technique using the side of the ''arc flame''. Yes, flame, just like a Oxy/Acet flame welding technique. Back in the day, most small bore was gas welded. Doing so you used the side of the welding flame ''cone''. TIG arc flame is similar in that you have a arc ''cone'' from the tungsten. Angle of tungsten grind greatly effects that, as well. I'll await your reply. Jeff

[@siamdarkweldertigwelding5874]

Hi, Judy. I just order your TIG finger and Strong hand mag tab from you. I want to support your channel because I've been learning many things from your knowledge and your welding experiences. Thanks again for your dedication, Welding. /// Detroit Dark Welder.

Love those Piranha grinders! The 3's are awesome but due to cost I'd go with the 2 for home use. Great video. The cut and polish was super cool to see and the arc shots were great too.

[@PelicanIslandLabs]

There are a lot of youtube wannabe welders but only one mad weld scientist and that's Jody! :-)

[@rognd8090]

best video i found in internet about Tungsten Electrode Grind Angle

[@bcbloc02]

I assume this also holds true that the bigger the electrode the greater the heat input to the part?

[@Freisein.]

Such an interessting Video. More tests about the Angles would be nice !

[@d.gosset4745]

Jody such a great teacher. I've learned so much from this old timer

[@chraso]

weldingtipsandtricks Can you help me in the difficulty? I have two brass pipes with thickness of 0.033"(or say 0.83MilliMeter) how much Amperage, what & how much gas I should use? Although I have learn from this video that I don't want to penetrate deep, so I can use a more angled.

[@rogerrascal8632]

great shoot Jodi, is it possible to the same tests for aluminium if you haven't already. I don't seem to have an issue with DC arcs or welding, but AC is a whole new bucket of problems.... thanks

[@dtrrtd774]

that was really impressively sciency with all the strict controls on the variables from the angles to the gap and weld speed. very nice test, good info. Did wonder if the IR measurement of temperature pointing at the shiny metal surface really made the measurement of the metal or the reflected room temperature. Emissivity and all that.

[@hassenfepher]

I’ve known about you for a long time. I’ve seen a few videos. My thoughts were always “meh, hes no TOT”. I finally bought a tig welder…. It’s like night and day! The same stuff has completely changed into useful and engaging science! I feel like i should apologize for discounting your videos earlier. I’m sorry sir. I will now be binging your back log trying to figure out why i can’t weld 90s in 1/16 aluminum. Thank you

[@djtoo7]

Ok for use newbees I see the 3 different grinds I like the first two but u didn't say what one is better for doing what? Thx Dan

[@rascalwind]

Jody, What would this same test do with a higher voltage? Could you use a higher voltage with blunt or ultra sharp taper to get better weld nuggets in certain applications. A higher voltage if you had to do aluminium with a blunt electrode?

[@TractorWrangler01]

I love this kind of tests. Thank you for taking it all the way through to the acid test. Great Video!

[@joe1010011010]

Super interesting video, my only criticism would be that im curious about the effect of a rounded tip

[@JonathanAldrich82]

Thanks for this. I just had my first DIY/TeachYoSelf Mig welding experience the other day and I find your videos great for learning things.

[@bchant19]

a bit of a shame that the weld cross section didn't show up that great on the video but a very interesting video as always Jodie.

[@PyroShim]

It is always good to confirm the theory in practice. Thank you for sharing.

[@mbdtw]

Thanks Jody, I'm a newbie and have been grinding my tungsten like the second example. I'll have to give the other types a try as well. interesting to see the differences in penetration.

[@Stainlessslayer]

I have no idea how to tig weld but your videos make me feel like I could👍

[@cons.bor.]

Excellent video,but i thing that you could have better results and no secondary energy jump point with the third (super pointed) tungsten if you use helium or argon/helium mix instead of pure argon.

[@HisKidd2]

Hey there Jody. I was just wondering about a non tapered tungsten? or maybe a taper on the very end, then flattened a bit. maybe it is not something that could ever be useful. I am a noob at tig it was just a thought. .

[@TheDuckofDoom.]

I'm curious about the effect of a double-bevel grind, like many knives use to achieve a low angle profile without an overly thin weak edge. The extreme of multi-bevel being a convex grind, and the two extremes of convex being a half circle on the strength oriented end and a simple flat grind on the thin/sharp end. The extreme of a double bevel electrode would be a flatted tip, I suppose. For an electrode I would think the transition between the two bevels would be somewhat important, in degree of change, position from the point, and finish(rounded, buffed smooth, or hard and sharp). You would probably want the position of the bevel transition either fully clear of the plasma or right down in it[flatted tip eg.], but not too near edge/transition of the plasma cone especially if it is a hard chine.

[@rockabillyredneck13]

Jody, I just purchased my first TIG Welder. It's an Eastwood TIG 200. No matter what setting I use, it absolutely destroys 2% lanthanated tungsten. It will melt completely away instantaneously. Thoriated and pure Tungsten work fine. What could cause this?

[@tptrsn]

AMAZING video Jody, thanks!! I guess it's time to revisit some blunt'er tungsten angles.

[@PANTYEATR1]

great video Jody. I usually always needle sharpen my tungsten when welding ferrous metals for no reason at all except I felt comfortable with it. now I see that I can possibly weld better with a blunt tip. I wonder what the effects are when using A/C current and welding aluminum??? thanks for the lesson.

[@johnguerriero7283]

Where can I buy a tungsten grinder like yours with the adjustable angle holder?

[@million2847]

Love this video, a lot of my own questions were answered, I have not been to school for welding but trained on site and have been taught bad information and techniques. Everyone there grinds sideways and to a very long point

[@JRo250]

It would appear the sharper electrode presents higher flow resistance, hence the second arc up higher - what Jody calls a 'halo'. I would guess that reducing the amperage would reduce the second arc/harmonic.

[@harrybrown4815]

on the acute-angled electrode, you said there was a halo effect. To me, it looked like plasma discharge which would explain the low penetration in the metal as electrical energy was being wasted in the plasma discharge instead of being a focused arc. But that is just my observation.

[@turbocobra]

I am nothing like you. You are an expert teacher/welder and I can barely stick 2 pieces of metal together! :) Very good comparison, interesting results for sure... thanks for the video Jody

[@timmwhite9218]

....watch, go practice what you've seen, repeat! Had opportunity to learn to weld myself starting with just running 6013 in position beads in H.S. shop back in 1975/76. Much practice, some work related experience since. Got to be an instructor to adult and H.S. students here local to where I now live....not welding!, ( instrumentation, core, and construction management.) I regularly used KZbin videos as an integral part of the C. Mgmt. H.S. classes (plus much lab time/hands on) and that's how we discovered Jody's neat site, products, and videos!! Great stuff, several of my students came back for 2 to 3 more semesters, several got 6G tig and stick pipe certified and a couple now earn more than I do!! : )'

[@number1XR650Rfan]

Jody thank you for what you do, once again. I could have watched this video before starting the night shift yesterday I'm 100 percent positive I would have been better. now I have more knowledge just cause you enjoy doing this.

[@ExzLLLL]

@weldingtipsandtricks God bless you Jody I've been watching you since I was in community college about 5 years ago, your videos helped me get my first welding job and I still watch you to this day. Hands down best welding channel on the internet if I woulda known about this channel out of high school I woulda bought a multiprocess machine and got the Same education that I did at community college.

[@austinthemm6399]

[@bobbauvian7700]

Hay there bud, I was over at the website, I want some of those clear lenses. but I see it says that they are for a numbered torch. How would I know what torch number I have? I am running a miller syncrowave 250 DX and am using the same torch it came with. I see the diagram with pictures of torch tips. But I am little confused about it. for example this item: Furick Jazzy #10 Glass TIG Cup Kit (for #9/20 and #17/18/26 style torches W/ Adapter kit) does this cup fit both style or I got to choose the cup that fits mine. if I got to choose the cup for my torch, I don't see the choice.... I think my torch is number #9 or 20.

[@ChrisB257]

Once again Jody - an illuminating and useful demo. thank you.

[@joandar1]

Well said Chris, John, Australia. PS: I learned a lot from this, as usual from Jodie's Videos'

[@BisdremisKostas]

book says that cone length should be 3 times the diameter o electrode ... looking more like the needle sharp.but as i see now better blunt than sharp, thank Mr Jody , have a happy 2017.

[@sethwalk2670]

[@jackmasse8227]

whats the make and model info for that tungsten grinder please. also did you see Black Stallion stole your Tig Finger and called it the Flak Finger?

[@scottaero]

good info , better to see the results first hand and well, no question here, Thanks a ton Jody

[@MonkeyFabGarage]

Love head to head stuff like this! Thanks for your time Jody.

[@blankreg9890]

Great vid. I weld 16ga 304 2b stainless all day, no filler, and am always interested in what can get me the tightest arc with the most heat focused on a pinpoint area. 'Always looking to get good penetration without a wide puddle.

[@16vastraturbo]

great video... what machine do you use to sharpen tungsten like that again??

[@jwboilermaker]

If you haven’t done a video on flat tip electrodes and prep angles, this would be a good one to do. My experience with a flat tip on the electrode increases penetration. Combine that with a different angle of preparation and see what you come up with.

[@YszapHun]

I guess the very sharp edge of the third electrode had such a high temperature (=and ohm resistance) that it explains the arc coming from a few milimeters above the tip. I believe the heat was not that concentrated and that is the reason why the third bead was narrower.

[@cousineddie7898]

Hi Jody! Thanks for doing this video. I think you may have hit upon a problem I'm having, that being how the arc "dances" around my tungsten like it's searching for something. I grind mine on a dedicated fine grit grinding wheel, holding the tungsten vertically and pointing down in the same direction as the wheel rotation. I wonder if I should he holding it horizontally and changing the direction of the wheel striations on the tungsten?

[@AlHackel]

l always kind wondered about this. Thanks for the well prepared test. Next question how does torch angle effect things? I know sometimes when welding around tube frames I have to make do with less than ideal torch angle.

[@emanueljohnfalzon6724]

Hey Jodie thanks for good work. What are the best welding books u recommend? For stick mig and tig? And weldaility of metals?

[@NathanClevenger1337]

[@jboard146]

Very good video. Learn something new all of the time. Going to use a slightly more blunt grind in the future for most of my work.

[@krzysztofkarolkiewicz8237]

hello, friend, what aluminum is used in welding, I ask for a sybole because it's so nice to you, thank you

[@phillean]

Thanks, I learned some of this in evening classes but you have taken it further.

[@NoExtent]

That halo is trippy. My theory is it might be creating a vacuum and pushing away the argon from so much heat or pulling in small amount of oxygen. Retest it with different variables of argon flow for that needle one.

[@pvcpropulsion843]

Hey there I got a question I take metal shop at my school and I've Ben working with are miller ac square wave tig and ark welder but we just youse it for tig my main problem is when I get the arc going it makes my electrode tip turn into a ball every time I go sharpen it. It always does it and advice ?
