Tig Welding penetration is affected by the angle of the tungsten grind.
There are several charts in text books and on web sites that depict the penetration profile caused by different grind angles of tungsten electrodes.
I like to see things for myself so I tested 3 very different angles on pieces of 2% lanthanated electrodes ...all 3/32" (2.4mm).
I let the piece cool completely in between beads and kept the arc gap the same for all three beads.
Travel speed as constant too on a welding turntable.
I cut the beads all the same distance from the start point and polished and etched using a stainless steel heat tint removal solution.

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.

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.

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 🙃

@d44n19 7 лет назад

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 7 лет назад

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

@somejimmydude2121 7 лет назад

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

@melgross 6 лет назад

A lot of us aren’t like you. But we watch your videos because you are an ideal for us. So I can think that while I won’t be like you, maybe I can become 50% of being like you. Seriously, thanks for the wonderful instruction over the years.

@MrNextdoorscat 4 года назад

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

@hiseminencetheholymacdiarmada 7 лет назад

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 4 месяца назад

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??

@billsmith5166 3 года назад

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

@Derrick-lk1zo 5 лет назад

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!

@BobSmith-mc7uq 6 лет назад

Of all the welding channels on RU-vid...this is the BEST! Class is never over.

@josstark8124 4 года назад

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

@mski349 7 лет назад

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.

@taohawaii 7 лет назад

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!

@luvkountry 4 года назад

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.

@dave-d 7 лет назад

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.

@dannyhanny1191 7 лет назад

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 7 лет назад

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. : )'

@bugdozer 7 лет назад

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 6 лет назад

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!

@TYMWLTL 4 года назад

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.

@timmwhite9218 7 лет назад

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. : )'

@michaelcostello6991 3 года назад

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

@hassenfepher 3 года назад

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

@mattgrover3096 2 года назад

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.

@TractorWrangler01 7 лет назад

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

@scottcarr3264 7 лет назад

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.

@gregeizans1334 7 лет назад

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.

@mbdtw 7 лет назад

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.

@metzsmayhem6832 7 лет назад

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.

@jboard146 7 лет назад

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.

@turbocobra 7 лет назад

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 7 лет назад

....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 RU-vid 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!! : )'

@austinthemm6399 7 лет назад

just ordered a basic Stubby kit! can't wait to give it a try, thanks for the content. 🤘

@Aint1S 6 лет назад

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.

@scottaero 7 лет назад

@tptrsn 7 лет назад

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

@jlstazz 6 лет назад

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

@stefanhertweck 7 лет назад

Great video! Thanks for visualizing and explaining the welding processes and for sharing your insights.

@million2847 7 лет назад

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

@ExzLLLL 7 лет назад

@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.

@michelleswanson3169 5 лет назад

Thank You! I was a needle sharp guy til now!

@papahajek5383 7 лет назад

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.

@NathanClevenger1337 6 лет назад

I really like the long taper for manual TIG welding. I use my Arc-Zone sharpie with the adjustable angle option. It works pretty good for what it is.

@osulxa 3 года назад

Great video. Thanks for sharing. Looks like the secret is that tungsten grinder.

@phillean 6 лет назад

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

@dtrrtd774 7 лет назад

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.

@nardzenalisan2317 3 года назад

@berntsteinmetz8564 3 года назад

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

@MO-zu9xq 3 года назад

Going to go for a flatter grind angle from now on... Thanks!

@jwboilermaker 6 лет назад

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.

@leonardpearlman4017 6 лет назад

I bought a welding positioner because of these videos! Would like to see at least one more here, the good old balled end of history. Just because! It's easy to prepare, right? Might be more durable, too.

@leonardpearlman4017 6 лет назад

And while we're at it and using a nice precision tungsten grinder.... How about the fairly common taper with a flat on the end? Like a used pencil. I read once in a very early book about TIG welding that electrodes were sometimes ground like a chisel or screwdriver! I keep wanting to try this....

@NoExtent 7 лет назад

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.

@jaydendavis7596 4 года назад

I sure did learn a lot about how the tungsten affects my everlast tig welder.

@mr.renovator4859 5 лет назад

This is very good and well carried out experiment. Just a comment using an IR thermometer for checking heat on a shiny piece of metal..... Beware folks, the so-called emissivity for shiny metal is very close to 0.1 (this calls for a reflectivity of 0.9). This means that an IR thermometer must be adjusted to compensate for this fact. Otherwise, the temperature reading will be far too low as Jody´s piece of metal only emits 10% of the heat energy. It is very common people use IR thermometers on too shiny or too small surfaces. The latter means that background heat radiation gets into the optics. This of course give wrong readings of objects too. Best regards /Jan

@johnt9810 7 лет назад

Great video and interesting info. when I was learning TIG in welding school and doing open groove joints I found it easier for me to run my root with a needle sharp tungsten. That might have had something to do with what you showed here. Good stuff.

@chrisholifield8571 7 лет назад

awesome. I've always used the needle sharp tungsten, I may try the more blunt grind and see how it works for me.

@brianlucey4402 7 лет назад

@GogebicYooper 7 лет назад

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?
