Cast-Iron Welding Electrodes

La description

Metal filler compositions based on manganese and nickel for the welding of cast iron are disclosed. The filler composition preferably contains about *5 to *0% manganese and *5 to *5% nickel. The filler compositions may be incorporated into a welding rod for Shielded Metal Arc (SMA) or into the welding wire for Gas Metal Arc (GMA) welding or added as metal powders in Flux Cored Arc (FCA) or submerged Arc (SA) welding. The compositions are particularly useful for welding gray and ductile (nodular) cast irons.
