Hardfacing MIG Wire

Hardfacing, or hard surfacing, is the application of hard, wear-resistant material to the surface of a component by welding, thermal spraying, or a similar process, mainly to reduce wear. Hardfacing is used on original equipment as well as for the repair of worn components. Hardfacing MIG wire is available in wire spools and is applied using MIG welding machines as regular MIG (or gasless) welding wire. Compared to stick electrodes, hardfacing MIG wire is faster to apply, more efficient and more cost-effective. What preheat setting should I use for hardfacing? As a minimum, most applications require preheating to bring the component to room temperature of 21 - 37°C.  Medium to high carbon and low alloy steels may require higher preheat to prevent underbead cracking, weld cracking, spalling, or stress failure of the part.[/vc_column_text][/vc_column][/vc_row]
