FCW K250
Seamless copper coated tubular wire for gas shielded metal arc hardfacing
Description & applications
• Seamless copper coated tubular wire for gas shielded metal arc hardfacing
• Excellent weldability
• Surfacing or rebuilding parts subjected to high compression stresses and high impact
APPLICATIONS
FCW K250, up to Ø 1.6 mm, is suitable for downhand as well as for positional welding by adapting transfer mode and welding parameters as for solid wires
Examples
Rebuilding and buffering of forged or rolled mechanical components: transmission shafts, rolls or chocks for steel making, roller bearing seats, rollers for gantry cranes, gear teeth, forging tools and dies.
