a customer had a set of headers off me, he then bought a torque hammer silencer, which didn't match up to my collector, he took the the exhaust to a local stainless exhaust specialist, their version is on the right, proof you can polish a turd, they wrecked my collector and bodged some bends on, needless to say he wasn't too impressed, so he had me make a new collector and pipe that fits, and looks a sight better, also it's the inside of the pipe you pay your money for, they don't purge their pipes, i purge all my welds  theirs  mine  | ||

Does purge mean putting inert gas inside while welding? I guess it would make sense since it's every bit as hot as the outside. | ||

Stainless steel "sugars" or bubbles if you don't purge the back side of the weld with full penetration. Looks like black sugar is the best explanation, so yes, purging the inside with argon is recommended. Some guys can get away with not purging, really depends on who's doing the welding. | ||

if you are welding thin gauge stainless tube and want full penetration and want it to last you need to purge it | ||

I am used to seeing purged welding for dairy and food sanitary tubing and that looks as good inside as outside. | ||
