🔥 TIG Welding 1.6mm Stainless Fillets (Viewer Request)

We had a request to weld up some 1.6mm (16 gauge) Stainless Steel using the TIG process and no pulse. The trick to TIG welding thin Stainless is to have a fast travel speed. The slower you go, the more oxides you are going to get, so hammer down and go!

love that you showed you actually slipped rather than doing another take good weld tho

[erikdude]

The information and knowledge in these videos is only half the reason I watch them, the other is the banter between Bob and the Camera Guy.

[MP-zvfm]

RIP MR. BOB Watching again and again for review. Glad to see Bob still teaching.

[kevinmarshall]

My favorite weld instructor. Always great information.

[scottcarr]

Thanks Bob, These are the kind of video's we need. Nice work.

[mightylaidlow]

Maybe you can do a video on what size tungsten and cup to use per material size and or weld joint? Any benefits to one over the other? Thanks as always, Bob.

[CountryAireDesign]

I'm going to be welding up a stainless plasma table water tank tomorrow same material thickness, thanks for the refresher!

[vaithilingamr]

I am really very grateful to you Mr.Bob

[karlofffstandford]

Thank you for the demonstration it was very helpful !

[ericpeppers]

I started with mig but now trying to learn oxy/ acetylene welding I would love to see more videos on it

[lakeschoolrestorationchann]

Thanks for the video as always. Sometime you should do a video on .120wall tubing (as commonly used in roll cages and off road parts like axel links/bumpers/etc). I have some projects I want to tig weld up for my truck soon and I am a bit confused. It seems it's recommended to do a full penetration weld on butt joints. Yet on notched tubes I see guys welding in other videos they keep the gap in the joint to a absolute minimum. I don't see how they are getting full penetration in tig in such cases without a gap. I could run way over amperage and I can't get full pen with a 0 gap. They aren't beveling the tube ends either. Any thoughts/advice/video would be great.

I've got a pretty cheap harbor freight 165 amp Tig. I mainly got it to do thin stuff like 12g steel horizontal welds. Thanks for the info

[ozzmann]

Can you also do tig on 16 gauge outside corner joint? I am trying to make a small purge box for small parts that need major argon backing I’ve got an idea just haven’t done much will stainless outside corner joints at such thin gauges

[jamesdaniel]

Can you do that with 1/8" tungsten ?

[ozbuds]

When you are tig welding could you tell what type of tungsten you are using? If you only said what color that who be very helpful. Thanks a lot and I look forward to the next video.

[JeffPaisano]

Bob, what would you change here for 20 Gauge Stainless Steel? Amperage only or cup size as well? Fillet size? My set up is same but 3/32 fillet on 20 gauge and struggling to control the puddle. Thanks for this video, working with it in the shop.

[CascadePacificNW]

I can’t seem to keep my heat in control. The whole weld turns grey except the last 1/4” to 1/2”. Im welding about 3/32” stainless. Ill turn my amps way down but I have to stay in the same spot for a long time it feels like to get the puddle going and then the base material seems to get really hot just as the puddle gets moving a little bit.

[michaelcostello]

was this a number 6 with gas lens or just a number 6 ? im a newbie at welding

[jessedeantindall]

I took what in thought would be an easy test for a job this mornin and failed it. I just had to do two horizontal fillet welds just like this and then weld two cupons together fusing just the base metal with the tungston. Im a rookie at TIG welding and i was used to just tiggin on thick stainless pipes, that thin stuff is a different beast. I can see what i was doin wrong. I was wonderin If i hold the torch with my right should i be pushin or pullin the puddle on this thin stuff? And i noticed hes just runnin the bead along really easy without moving the cup at all i was taught to "walk the cup" id appreciate any helpful advice on the subject. They said if i got in a little practice or something and wanted to retake it i could

Took a Stainless TIG test yesterday, bombed it (only second time I've welded Stainless). I was having two issues;
#1 vision- seeing what was going on clearly (I guess a 1.0 or a 1.25 cheater lens would help with that)
#2 getting the puddle to form and then move along. I had a similar set up to the one in the video. I set the machine to about 95 amps and gave pedal until I had a puddle. I tried to move out and things just wouldn't move like I would want. It seemed I either had too much heat or not enough and blew out the joint several times. I don't seem to have this kind if issue with carbon. The only two times I have ever welded stainless have been on tests (probably 90% of my problem). If I get another shot is there anything specific I should "look for" when attempting to initiate a puddle and then move out down a fillet or lap joint?
Thanks for the great videos.
