The welding rod is composited by Cemented Carbide Grits, Spherical CTC and CTC. The layer has higher impact resistance, better wear resistance and good fluidity than other rods. Wear resistance is 6-7 times better than others. Tested by ASTM G65 method. Mainly tungsten welding rod used for oil method drill bits, such as tri-cone bits, steel tooth bits, PDC bit, etc. by oxyacetylene with weak carburizing flame. Our company can provide different best welding rods with high performance wear resistance.
