Tig welding s/s tanks 1.5mm

Have started welding dump tanks together but they warp really bad! Any suggestions on how to stop this? Normally weld around 40 amps 10 lpm argon.

Welcome to the forum! I weld on SS beer kegs for home brewers and ...ahem...others, 18ga. material. Kegs have alot of rounded areas so they don't warp too bad but a good trick is to lay a wet rag near your weld area to draw out the heat. SS doesn't conduct heat worth a damn and it builds up, thus warping. Run shorter beads and be vigilant about removing the heat and you will, at least, minimize warpage.

Ah that's a good idea. Will try this next time I put one together. Thanks for your suggestion ☺

What type of welder? Tungsten, etc...

I weld a lot of 1.5mm around 55 amps, get in, get out, weld pretty fast with .030" filler. I also will pulse fuse weld stainless at 60-65amps 10-500 pps, 1/16" tung, #8 gas lens

Bradles08,

PAY ATTENTION to Rick_H. He does food-grade stuff like this as his main bread-and-butter, is (or is nearing?) a master of the craft, and can help you.

Don't we all!

Anyone who tells you he's a master of his craft is done learning, and is deluding himself. It's for others to define you as a master.

"Do you see a man who excels at his work? He will stand before kings. He will not stand before unknown men."
Proverbs 23:29 (Gideon version)

"Seest thou a man diligent in his business? He shall stand before kings; He shall not stand before mean men."
