This was a scale prototype project for San Diego State University Engineering Department. The vessel will be used to house gasses which will react to sunlight and build up pressure and heat. The pressure and heat will be vented and used to spin a small turbine which will generate power. This is a very dumbed down explanation, but the concept is there. If it works a much large pressure vessel will be built. This particular one features series 150 flanges, a 3/8″ pipe section, and a cast dome.
For precautionary measures we take the time to lay a root pass with a TIG to ensure proper sealing. The vessel is then placed on large welding positioner where it was welded with with AWS A5.20 / ASME SFA5.20 E71T-1 welding wire with our new XMT 350 CC/CV and 12VS Extreme suitcase. This setup is perfect to lay down a nice fat single pass weld.
