I posted a few pictures from work a while ago and got a pm about posting more. These are from the last week, changing out worn sections of superheat tubes in a powerplant boiler. The other person is my welding partner. These are all 2 man welds, tig root and 9018 out. The sides of the root one guy will run the TIG torch while the other runs the filler wire. When sticking a horizontal weld it's one continuous weld, there are 2 stingers on a Y running off the same machine. Coming around the sides we steal each other's arc and keep going to eliminate restarts, and lower the chance of porosity. 100% X-ray, and they're not happy when you get a bad shot.
I'll take some more pictures tonight, I thought I had more on here.
