Cemented Carbide Welding Rod
The silver white tubular electrode was filled with cemented carbide particles in low carbon steel pipe by cold rolling steel strip drawing method. It provides excellent wear resistance and impact resistance welding layer, especially suitable for surface surfacing of oil drilling and natural gas geological tools. Cemented carbide pellets: 65-70%; Mild Carbon Steel: 30-35% Diameter of welding rod: φ 3.2 ± 0.3; φ 4 ± 0.2; φ 5 ± 0.2 Electrode length: 600mm Hardness of welding layer: HRC ≥ 60 |
