Preheat Requirements for 1045 Steel American Welding

Can 1045 steel be welded?Can 1045 steel be welded?DWHA; Yes. In general, 1045 carbon steel can be welded provided preheat requirements are followed closely. In some cases a stress relief or post weld heat treatment may be required. The lack of preheat is normally the cause of most weldability problems with higher carbon grades of steel.ASTM 1045 Weldable? - Metal and Metallurgy engineering Preheat Requirements for 1045 Steel American Welding (plate) SUGGESTIONS FOR PREHEATING STRUCTURAL STEEL
