Stainless Round Bar
Posted: Sat Nov 01, 2014 3:15 am
I'm still in the early stages of learning to TIG so doing little projects like a torch holder. Making it out of 5mm stainless 304 round bar.
My question - When I weld two pieces parallel to each other i.e. down the valley between them, I get a really dull finish around the whole of both rods. I believe this is the Chromium going dull as there isn't enough argon covering it? I'm using 1/16th tungsten at 50 amps (wondering if this is too high) with a gas lens and #7 cup with 12cfh. Filler is 308L doing lay wire and sweeping motion between each side of the valley. I've got the piece mounted out the side of a vice so wondering if I'm just not getting the gas coverage around the whole piece.
Any suggestions?
