I'm not a certified welder in any way, shape or form. Mostly self taught though I did take an evening class at a tech school once. I do 95% TIG on steel with my Syncrowave 250.
I have a project that I need to do which is a small pressure test vessel. Max operating pressure is 150 PSI, air only, at least two safety valves. Rough design is about a 12" length of 8" dia .5" wall steel pipe, fixed welded on base plate and a removable top cap.
Figure the top cap should have say six bolts to secure it, most likely hand knob style on a loosen and swing to the side out of slot in cap type arrangement for convenience. The top cap will also need to have a view port, presumably 1" lexan well reinforced with a couple steel cross bars.
Recommendations on how to do this safely? Am I crazy to attempt it? It's fairly low pressure and small enough to be overbuilt without excessive cost. Were I able to do this as a hydrostatic chamber I'd be perfectly comfortable, but as an air type chamber the potential catastrophic failure mode makes me nervous.
Thanks,
Pete C.
