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
