Composite Welds with Tungsten Carbide
RanMIG Carbide Overlay
Tungsten carbide particles dispersed into a molten weld metal matrix to form a highly wear resistant deposit, especially suited for ground engagement tools. We recommend Rankin's tough iron base or nickel base wire for the matrix wire.
Oil industry: drilling tools, tool joints and drill collars. Mining equipment, construction equipment, and agriculture equipment.
