Low-alloy wire stands up to high-strength welding applications
Lincoln Electric has introduced Metalshield® MC®-80Ni1 low-alloy, metal-cored wire. The wire is designed to produce high strength and toughness and H4-diffusible hydrogen weld deposits required in such applications as structural and heavy fabrication or other high-strength welding applications that require a tensile strength of 550 MPa.
Deoxidizing agents minimize pre- and postweld cleanup. Charpy V-notch tests show the wire can exceed 35 ft.-lbf. at -60 degrees F.
The wire is suitable for semiautomatic and robotic applications. It is available in standard diameters of 0.045, 0.052, and 0.0625 in., packaged in 500-lb. Accu-Trak® drums and 33-lb. plastic spools.
