D707 Tungsten Carbide Surfacing Electrode Model: Edw-a-15

 D707 tungsten carbide surfacing electrode Model: EDW-A-15 
Description: The tungsten carbide surfacing electrode of carbon steel core depends on the excessive alloy of tungsten carbide in the coating. The metal content of the surfacing metal is 40%-50%. Because the coating is thicker, the sleeve is longer and the welding rod is red. After the drug is easy to fall off the small piece, using DC reverse connection, a small current.
 Uses: Used for surfacing welding mechanical parts resistant to strong rock wear, such as concrete mixer blades, bulldozers, dredger blades, high-speed sand mixing boxes, etc.
 Deposited metal chemical composition /% C 1.5-3 Si≤4 Mn≤2 W 40-50 Surfacing hardness HRC: ≥60
