This is what I purposed at my place of work. That we put the tube in the 2g position. Put back pressure on the tube with argon. And orbital weld them with a magnatech 810 head set. This should eliminate the manual tight weld.

Are you certain the tungsten is large enough for the amperage you're running? Too small a tungsten will spit into the weld, even microscopically. Was there any NDE after the orbital pass, to confirm it's the GTAW making the inclusions? I'd be suspicious, all GTAW factors controlled, that the NDE in...

3/32 lath tungsten. Measuring with my Mics about a .020 flat. I'm using a piranha grinder. Sorry should have mentioned that.

Hello, I've been with my current company for 6 years in March. The method of welding is TIG at my place of work. We do Land Based Turbine componets, lots of tiny welds..lots. Recently we picked up a new component. One of the operations involve sending it out to XRAY. Out of 10 parts we ship to XRAY,...
