Sch 40 904SS pipe test with Inconel root
Posted: Sun Dec 19, 2010 9:46 am
We are welding 904 SS pipe, 1/8'' gap, tig all the way with a 1/8'' inconel filler wire. We are between 120-150 amps. Is this the preferred set up for this? I haven't welded with this material before. We are also using pure argon. Is it better to get a helium mix? Any hints for welding with this material? Thanks, gmanlu716
