NI-ROD 55 Welding Electrode is used for shielded-metal-arc welding of gray, ductile, malleable, and Ni-Resist cast irons. It is also used for welding cast irons to various wrought materials, including carbon steels, low-alloy steels, and nickel alloys. The electrode is especially useful for welding heavy sections and high-phosphorus irons. NI-ROD 55 Welding Electrode can be operated in all welding positions. Power supply: direct current, electrode positive is preferred although alternating current can be used. This datasheet provides information on composition and tensile properties. It also includes information on joining. Filing Code: Ni-499. Producer or source: Inco Alloys International Inc.
