🔥 TIG Basics: Thin Plate Butt Weld Practice

[@MoparStephen]

Great video - thanks for not editing out the mistakes too, it's great to see someone with your level of experience can still have problems, or make mistakes.

[@PelicanIslandLabs]

Very informative video. We learn more by seeing you go FROM unacceptable to acceptable welds. Well done!

[@rjbailey2010]

This video is superb. Watching someone make 'mistakes' but then know and explain what the problem was and how to fine tune the solution, provides exactly the information missing when at home trying this out. Thank you.

[@gambitdesert8500]

@@rjbailey2010 heck yeah it helps me for sure great vid

[@natashamusil9187]

Thank you camera woman for making him do this. This is my worst joint type on all processes (right now) and I'm a little relieved that even a career welder can struggle with it.

[@girliedog]

No apologies needed when your showing us the nuances of tig welding in a clear and concise manner.

[@MFHealy]

Excellent instruction, thank you. I am very new to welding - six classes into an intro to welding continuing ed program. Still running stick weld arc beads by the mile (feels like it anyway), horizontal, vertical, overhead, zipper, etc. All the mig/tig, flux core, solid core, etc., is all still unknown to me, (that comes in the second course this winter). Straight-up instruction, honest, direct, no fancy graphics, sound bites, other distractions. I am addicted, looking forward to more.

[@markcnc]

love the shots where you can see the amps on the machine, very informative. Kudos camera person!

[@shaneburns6443]

Absolutely! The twin shots of arc length vs machine output is mega helpful!

[@Steve_Just_Steve]

I miss these kind of shots! They deserve the kudos. kzbin.info/www/bejne/o4uaXmCHgct1hNU

[@leeveinotte894]

Steve just Steve deffinitely. I think they changed camera operators

[@davedunn2124]

Well I say the new camera girl is doing just fine. She will learn to get in there. It is a lot harder to do than people think to get those good shots. Bob, I learn something on every single video. One day could you give us a quick run down on different weld configurations and what their called. Butt, fillet, etc. maybe a quick lesson. For us beginners. Fine job Sir.

[@bobmoffatt4133]

Dave Dunn Good feedback. Thanks.

[@sparkywelder3690]

This video provided an "ah ha" moment for me. After watching it a few times, I realized that I had my amperage turned up way too high. I'm trying to learn to use a foot pedal and not being much of a TIG welder to begin with, I was just making a mess of everything, but then after watching Bob and looking at the current on his machine, it dawned on me that I had my current turned up way too high. I just don't have the skill to control the foot pedal with that much current set, even if it's appropriate to have the current set so high in the first place. When I adjust the max current to match the work piece, I have much better success so when I mash the pedal, my work piece doesn't blow away and the full pedal is where I should be with the work piece. It's night and day for me. I was ready to just call it quits with TIG and stick with SMAW, because I don't suck at it and I really enjoy the smell of 7018, but I have found the joy in TIG once again it's thanks to these videos. It took watching the video a few times and if I couldn't see the amperage on the machine, I might not have figured it out. Details are everything in these videos and the benefits to those on their way to mastery are priceless. Thank you weld.com and thank you Master Bob!

[@Thejoker_1o1o]

Started welding a few months ago and starting to do butt plates, very informative and thxs

[@parttime3724]

Can the camera get some closer shots of the key hole and weld pool like you had in the past? the way you manipulate the torch and wire helps me to see what i need to practice. thanks for all the help

[@Ghis1964s]

Good video. I'm an old welder, and last year I would've really use some thoughts/taught on how to setup a "crappy" (15y-o Lincoln 210Amps 25%) welding-machine to mig-weld around (butt-joint) rebuilding as new a manure tank. I've chosen gas flux-core as I'm used to rebuild/butt-weld 5/8" to 3" thick material on different machines (buckets/loaders&booms/bulldozers/farm-equipment/saw-mill rigs/trailer-trucks/shop-cranes/cranes/cast-iron casings/housings/etc... you name it). But all I could find was lap-joint this and that..... and I'm like, "What??? These guys are all pro-welders, and it seems they never once in their career had to do what I have done or need to do". I had about 3 sections to weld together which amount to some 80feet of all-around welding. And it was out of the question I could rod-weld these as the stick-welder my friend has is no good anymore (needs a complete re-haul as those machine were the best way back when etc). So yeah, after all my useless bla-bla-bla here (trying to put a context anyway), how would you go about mig-welding butt-joint 5/16" plates? (it's not pipe-line work though, so no scale-removing is needed. Lets just say it's like as if welding on a production-line or such) (yeah I know, production-line welding is not welding. I call this "gluing".... :-(

[@fozybear]

You show a lot of thick plate welds. I’m a coded mig welder from the uk and I also weld 4mm plus steel. I wanted to see if you could advise on car body repaired at 0.8-1mm thick. What’s best mig/tig and any tips. Thanks James

[@baranarslan8604]

I wonder how many kilometers has Bob welded when you sum up all the bead lenghts in his life.

[@jasonweishaupt1828]

I’ve been welding for years. Practice makes perfect. Lab welding is not that hard. When you take the lab conditions away, all bets are off 😂. My current project is 18ga door flanges and 20ga door skins on my ‘83 Caprice.

[@NB-ir1me]

I'm taking a community college tig class that's 6 classes 8hrs a class and seeing what NOT to do vs what TO do is SO HELPFUL!!!! Thank you so so so much I'm so worried I'm not going to be good enough or I'm not going to make it and seeing you make a mistake helps so much man I'm really worried about it I've done a very small amount hands on and start my class in 4 weeks so trying to gain as much as I can before hand

[@rvalcourtpersonaca]

On your roots are you creating a window or is the weld puddle penetrating through to the backside? Great video!

[@bobmoffatt4133]

Richard Valcourt I like to do both.

[@zangetsuzabimaru]

I just learned this 2 days ago. My job sent some us to an 80 hour weld course to master mig and tig and on the 4 total days of tig we get, we have to be able to do a perfect top down 4in butt on 1/32nd steel to pass both a visual test and a bend test, and after practicing it for 2 days, it feels impossible. Mig was so much easier to do. Using blue tungsten, have the machine turned all the way down to 40A and it still burns right through just trying to tack the joint together. Tig just feels like an impossibility to learn in just 4 days. What is the trick to this? You're blasting through it like it's nothing at all with perfect penetration and at a much slower rate I get huge gaps of no filler rod melting in, holes, and no penetration at all. What's the secret to this?

[@danbuffington75]

Would you do a braze or solder sheet metal butt joint? I'm fixing an old computer case that is about 16 gauge steel and it's really been an interesting project that others might learn from...

[@JohnDunn1969]

Hi Bob great job.

[@tra757200]

How do you judge your amperage with the foot peddle? I notice about 60 amps you said was too low then 90 was about right but I'm curious how does that look under the hood?

[@tomherd4179]

Would like to see more close ups of the welds you were verbally describing.

[@leonardpearlman4017]

is this a job for "back step" welding?

[@ВадимМузычко-у5м]

Bob hello show and explain the MIG / MAG welding technique in position 5G and 6G for testing

[@mixpick138]

I do enjoy your videos but you are either doing heavy duty plate or big pipes *in a controlled environment* (as you said) but many of us have thin plate 1/8" or so and have got nothing but gasless flux core to deal with it due to outdoor conditions. Are you afraid of the challenge or is it too beneath you? 🙂 Still loving your big boy vids all the same!

[@wanderleyapparecidovieira2282]

When I say thin plate tig welding ,it's a number #18 or #19 plate butt welding ! Can you make a video about it?

[@dabossdope2859]

Great welder!

[@harrishilson2201]

What the thickness of the plate?is it 2mm?

[@deertrackertv2532]

Could you do a video on some P90 Chrome

[@rickbrandt9559]

Honesty, we can be our own best critic.

[@randalljames1]

I think the plates closing up was a test... he should have started the first weld outside the tack... what I also learned was how to vary the tungsten gap was to "roll" the wrist

[@kwasg3]

Thanks for the vid Bob. I didn't quite get what was wrong with the first weld. I understand the exercise of root and capping the 1/8", but in reality, like building something, isn't this normally a one pass weld? Is there a merit difference between the two? Also, I do agree with the comment about video technique seems to have changed some. Hopefully camera girl learns the tips and tricks of past camera guy!.. But, onward and upward, as always! Thanks again. (NOTE: Lol all you industrial structural guys reference 1/8 as thin... thats the thickest we see!... I am practicing tig to do .045 sheet and some aluminum up to 1/8!)

[@paulmorrey733]

Cheers Bob

[@peterford9369]

So the gap closed even with a tack on both ends? Thats a hot fill.

[@dragthatsht]

Peter Ford it's because he started on one of the tacks. It melts the track and the heat pulls the gap shut. It would have happened at low temp as well

[@peterford9369]

charles streeter Ahh, I see. Was curious. I do torch work. Thought tig was so much sudden heat . Thanks.

[@Steve_Just_Steve]

I'm not sure what's been going on over there lately as far as the filming quality but I'm bummed to say it's really gone to crap. I really appreciate what you guys do but the quality of arc shots, pre and post weld joint shots have just gone way down hill the past few videos, like off the edge of a cliff. You used to get right in there with clear shots and adjust exposure on the fly and get the shots no one else does to really show Bobs technique and what the welds looked like as Bob was explaining them along with showing machine amperage. I mean look at the difference between this video and one like "Lay Wire vs Dab Techniques" or "AC Aluminum Pulse Welding". This doesn't even compare. What's going on over there? Please go back to whatever you were doing before! Thanks for the vids. Edit: Not to mention the out of battery deal! Come on!

[@arazusaysbah6784]

I have to agree. The photography in past videos was amazing. Not so much recently. I really miss the way the videos used to be. Thank you for all of your hard work.

That looks like .125" plate and actually a lot of us DIY'ers are welding .062". Is TIG not appropriate for welding .062" steel?

Big Papi Oh yes. And even way thinner.

[@ericr513]

Thank you !!!

[@Welddotcom]

You're welcome!

[@홍카야]

Thank you movie and nice of welding

[@larrysmall3521]

One suggestion. Please mention your tungsten size when you do the videos. We can see the current but we can't tell what dia tungsten you are using. Thank You. Even if you didn't get the weld the first time, the expert in you took one look and knew what was wrong and how to fix it

[@Steve_Just_Steve]

tungsten dia isn't that important. I know a lot of guys who weld just about everything with 1/8" they just sharpen it differently. You can weld thin metals with 1/8" if you put a sharp point on it. I use 3/32" for everything that it will handle unless I'm doing micro welding.

[@logihalm9077]

This help me

[@zackthomas2982]

I don't know that I would necessarily run two beads on metal that thin just barely put a gap in it and just fill it. if you put a gap it the metal at all.

[@michaelcannon5053]

big up bob

[@Aint1S]

Less than 1 mil, .003 to .004 sheet seems to be my curse. It's absolutely hard AF to start a tack on the sheet without blowing it out WITHOUT cheating. I can get it to tack up homogenous quick from each side and i can also see the arc stay on one side to keyhole both sides into a huge gap . Without oversized filler, it gets nasty quick to not have a larger initial puddle to push along. 20 amps is maxed out. Anyone care to share any information about technique. No plate backers as well, can't do it where it it's being welded as much as I would like to have them there to chill the steel. I've tried it with aluminum screwed to the steel, but the steel is pressed into a specific shape.

[@jamier6742]

Aint1S AUTOGENOUS IS WHAT YOU MENT?😎

[@Aint1S]

I can't seem to get it to happen without running it dirty. Ideally, I want autogenous. You're right though lol! Brain fart on my part. For some reason, I can't get it to play fair without a nice dab of filler to bring two together without that filler to start the run. The starting thickness is somewhere in .0030's before I have to get the zinc off of it and it drives me crazy doing this vertically overhead. Any pointers? Please! 🙏

[@caitlinleanna5028]

with thin stuff i will tack the ends starting my arc on the filler letting it burn back a little til it hits the piece then if it needs to be an autogenous weld i will do the rest that way, ive found the filler trick makes it easy to do thin stuff only bc that initial arc start tends to be to aggressive and blows right through but once the arc stabilizes itself it wont anymore ( just realized im commenting from my gf's account sorry)
