Introduction
HFK 150-G welding wire is a CO2 gas-shielded flux cored wire that produces some slag. Its welding performance is excellent without much spatter, the wire’s arc is stable, slag removal is easy, and the welding beads have a beautiful appearance.
Typical applications
The welding wire is suitable for high-precision surfacing, repair of mechanical parts, and cold-rolled backup rolls.
