Abstract
This paper contains experiences in the welding of Austenitic and Ferritic stainless steel with combination of welding process GTAW and SMAW. This investigation characterized the mechanical and chemical properties of weld metal in the Austenitic and Ferritic stainless steel. The selection of filler metal for welding the Austenitic and Ferritic stainless steel is based on the composition of the base metal (SA240 UNS S32304). For root welding GTAW processes ER2209 filler wire and subsequent layer SMAW processes with electrode with basic flux E2209-17selected for this investigation. These investigations are complains with ASME boiler pressure vessels codes. The principal goal of this presentation was to provide the solution for combined welding of Austenitic and Ferritic stainless steel to the application of fabrication of desalination tank and ship building.
