Long story short I have a tig that I've been practicing on for a little bit but cant seem to produce proper coloured welds, curious if anyone have any input.
I'm welding up a SS304 3" round tubing (16ga), using 2% lanthanted electrode with 65 Amps, using a #12 cup with my argon flow set at about 20+/-. I dont have the tools to purge the inside of the tubing so I'm coating it in Solar Flux "b".
My issue is whenever I weld the stainless it 95% of the time turns a grey color, after I'm done welding I leave the tig torch hovering over the welded area so it stays cover in argon. Is this just to much heat? I've tried lowering the amps but I seem to get the same results. I've attached a picture of one of my welds where I joined 16ga SS tubing welded to SS exhaust flange.
