Thought I'd throw this out and see what the pundits say. I have a project consisting of partially re-tubing a stainless steel heat exchanger. I had to cut off 8 half-round 4" pipes about 4 feet long to access the welded ends of the tubes. Tubes are replaced, tig welded in, now it's time to re-weld the half-round pipes. This is about 50 lf of horizontal weld, 1/8" wall thickness. I have about 50 lbs of 1/8" very good Swedish 316 stainless rod I'd like to use. I've never tried pulsed stick bu† this would seem to be a good application. Thin metal, horizontal weld, high rate of deposition. What should my settings be and is this likely to work? Thanks.
