      Holy.... mother.... of.... god. That's a crap ton of welding. That's probably more welding than I've done total.

      Forgot to mention, that was the second valve, all done by hand. The robot welded one was already insulated for pwht. 4 layers on the top, one in the back, and three in the seat. Last time these valve were worked was in 89.

      And for a size refrence, each bead, except for the corner beads, are almost an inch wide

      The weld prep left 2.5 at the top, and at the bottom, its about 4, but the way the valve chamber is designed, its probably closer to 10.

      Don't mind my shaky line.. I don't currently have a table in my garage and was not in a good position for this.. Ran a 3/32 tungsten and rod at ~180A with a #7 cup

      Hobart Handler 140. With a spool gun it'll do aluminum. It's cheap. And it runs off 110. It's the perfect hobby mig.

      More industry work.

      This time it's a gas turbine plant in southern Alabama. An expansion joint baffle in the exhaust keeps cracking, so engineering gave this to us as a temporary fix. Two units. I didn't get to play as welder much. Night shift got most of the welding work. I got most of the cutting off the old panels and prepping the new ones.

      The black lines are the cracks, where the baffle is falling down. One unit was still held on at the top, the seconds was completely broken.




      The plates we had to put on




      A few of the welds I did. Left handed weld, done with the right hand. It was supposed to be a 3/16 fillet, but some of the plates had a 1/4 gap between the plate and the base metal, thanks to the fallen down baffle.









      It's SS347, no foot pedal. It does not like to overheat. The one or two wavy spots are where I overheated it, being out of position a little. I had to do three stringers and a fillet, before the base metal would reach the bottom of the plate and I could tie it in together.

      I flew out of mobile yesterday. That damn thunderstorm left us waiting on the runway for a good half hour-fourty-five minutes.

      nobody posts anymore?

      Another industrial job. Coal plant in Oregon. We're replacing the pressed in valve seat with a pinned seat. I have to weld the pin guides to the valve casing. It's a stupid weld prep. Need to talk to corporate about this one.....

      Weld was 2.25% chrome stick welded 6g-****-me-in-the-ass-super-restricted. I welded the side against the turbine cylinder because I'm the smaller guy and can actually fit there.

      location guides are fixed to the alignment jig. Casing was heated to 450 degrees prior to welding.



      "prep". It's a nipple fitting at an angle on a round casing. You can't even really see the bottom of the prep. it's retarded.




      Like I said, super restricted 2.25% chrome stick. The only way to get to part of it was to bend the last 1.5" of the rod 90 degrees and use it that way.




      I'm not super happy with it, but considering I had to weld 50% of it upside-down, and the other 50% hugging a 450% oven, I think it turned out better than it didn't.

      It looks a lot better in person. Camera flash always makes stick welding look ****ty.
