D707 is a tungsten carbide surfacing welding electrode with low-hydrogen sodium, which adopts DCEP connection method.
It is more suitable for low current welding. The surfacing metal contains 40-50% tungsten and has high hardness.
It applicable for surfacing welding of mechanical parts with high rock wear resistance requirements, such as concrete mixer blades, bulldozers and pump blades, dredger blades, high-speed sand mixing boxes, etc.
