Cast Tungsten Carbide Welding Rod

The hard phase of tube rod is carbide pellets which leads to higher impact resistance and better wear resistance than CTC cloase rod. Wear resistance is 6-7 times better than others. Tested by ASTM G65 wear test. Mainly used for mining machinery, geological tools etc, by oxy-acetylene with weak carburizing flame.   Raw Material Compostion Irregualr Cast Tungsten Carbide Welding Process Oxyacetylene Welding/Argon Arc Welding/Atomic-hydrogen Welding Main Equipment Welding Torch/Oxygen Cylinder/Acetylene Cylinder Filling Rate 61±1% Hard Phase Mesh 30-40 mesh  Wear Resistance / HRC ≥56.0
