50:50 Hard Phase Ni Based Welding Rod

The Rod Welding Bar is sintered by CTC and Ni-based powder. The Ni Based Welding Bar CTC(Cast Tungsten Carbide) is in irregular or spherical shape with better wear resistance and the nickel alloy is in spherical or nearly spherical shape and has good wettability with cast tungsten carbide. The Ni Based Ctc Welding Bar Cladding layer has a higher impact resistance and better wear resistance.

Its Sctc Ni Based Welding Bar wear resistance and corrosion resistance is between tube rod and flexible rope. Mainly used on the steel PDC bit, concrete mixer blade, mud pump, miner chute, miner drill stem and mechanical parts of tunnel rock drill machine etc. Welded by oxy-acetylene with with weak carburizing flame.
