【Abstract】 304L stainless steel ( ASTM standard ), as an austenitic stainless steel with ultra-low carbon, has excellent synthetic functions and is the most widely applied stainless steel in the world. Based on the site practice and research work, this paper summarizes the technological features of 304L stainless steel welding, and puts forward concrete methods and matters for attention to resolve welding problems such as intergranular corrosion, interlaminar non-fusion, tungsten inclusion while striking arc and shrinkage cavity while arc suppression. So that, the welding quality is effectively improved.更多还原
