so i'm welding up (TIG) a custom exhaust header in 304 SS. the tube is 16ga and the flange is .5"
after running a corner bead around each tube where tube meets flange (i had to use higher than normal amps to get the thick metal to puddle into the thin tube), i managed to get a section of the flange cherry red. when it cooled it started to bend.
can i gas heat the other side to cherry red and have it bend back, or do i need to heat the whole part and blacksmith it back in shape??
thanks.
