yeah I seen that video and it use to remind me of someone I use to work with well his welds looked ok after sandblasting the stainless pipe but he would weld so dam hot. I can remember a time walking by him and the weld was solid black meaning of course to hot there was no color what so ever in his weld, each side of the weld the pipe was sunk in, not good at all. It sure made me feel better when the fitter would say thank you Chris for welding it because he wouldn't have to go back and wash my stuff to straighten it back out. You just can't weld stainless that dam hot. Sure the guy was fast but the welds were black like in the picture. I sure use to hate having to go fix that guys screw ups man it was agravating but at the same time i learned from his mistakes so it was all a learning experience
