Alloy C276 can be readily welded by conventional processes used for austenitic stainless steels.
When choosing a welding method, those that minimize the degradation of corrosion resistance should be used.
Gas tungsten-arc welding (GTAW), gas metal-arc (GMAW), shielded metal-arc (coated electrode) or resistance welding do minimal damage to the corrosion resistance of the heat affected zone.
Oxyacetylene welding should not be used because of probable carbon contamination from the acetylene flame.
Similarly, submerged arc fluxes containing carbon or silicon should not be used due to carbon pick-up. Minimum heat input consistent with suitable penetration should be used to avoid hot cracking.
Tips: about Weld Joints of C-276 Alloy
Weld joints design should be determined by practices set forth in the ASME Boiler and Pressure Vessel Code.
