Study on Local Dry Welding of 304 Stainless Steel in Nuclear Power Stations Repair

Abstract:

Article Preview

Local dry welding is an important water welding method with special advantages for good flexibility in nuclear power stations repair where operation spaces are usually very limited, and it can be applied perfectly by simple integration of a lot of welding processes with shielding cup. An underwater welding system chamber was built, which is mainly comprised of an underwater welding test chamber, and a hydraulic driven underwater welding device. Shielding gas is inflated to the small compacted cup to drive water and protect arc and weld pool. At shallow water of 100mm,Pulsed MIG tests were carried out to investigate parameters which are related to welding process of 304 stainless steel cladding layers. Welding tests at different depth indicates that although profiles of welds produced both at pressures of 5 meters water depth and at pressures of 15 meters water depth are perfect, but cladding layer at 15 meters is more narrow and more high
