Cast Tungsten Carbide Welding Rods are mainly used as Pile-Up welding on the surface of metal parts to enhance its wearability.General YZ20-30g with thick electrode surfacing work and work requirements from Scraping role of the parts and components; If required welding layer 3 to 4 mm, multi-electrode used YZ30 - 40g; Surfacing request thin layer formation, the best choice YZ40 - 60g or more granular tubular alloy electrode.
