The cold-rolled strip tube is filled with cast tungsten carbide powder. The welding layer deposited by this rod exhibits an excellent wear resistance, which is highly recommended to apply in the work pieces of road construction, mine exploitation, oil and deep drilling , hammer for feed crusher etc.

Surfacing Coating/Spraying/Cladding/Overlaying Technology is one of the crucial technologies to improve the service life of the work pieces. It can be used in the form of special treatment and machining on the surface of the work pieces to improve its wear resistance against abrasion, erosion, corrosion and heat significantly and increase the service life and achieve the repair purpose finally.
