Introduction:H08Mn2SiA is a kind of argon-arc welding wire for carbon steel. Because the welding wire contains elements like Mn, Si, etc., air holes and slag inclusion can be effectively avoided, and in the welding process, the welding wire has the features of good electric conduction, smooth wire feeding, less splashing, beautiful formation of weld seams, etc.
Application: It is applied to thin plate welding and back welding of carbon steel and low alloy constructional steel (for example 16Mn) in bridges, pipes, automobiles, etc.
