Description:
Weldman A1 is a hardfacing wire that produces a high strength deposit that work hardens rapidly under impact. Best used for buildup/joining manganese steels, carbon steel and low alloy steel, where parts are subject to impact and abrasion. It is self-shielding. It is often used in applications of impactor bars, railroad crossings and crusher rolls. Weldman A1 uses DC straight or reverse polarity. It has poor machinability, no surface checks, high impact resistance and fair abrasive resistance.
