The steel belt is filled with the iron alloy powder of chromium, molybdenum, niobium etc.and makes the different diameters of welding wire after crimping and drawing.   The flux-cored welding wires are widely used in the work pieces of cement, power roller, coal, engineering machinery, shield cutter, 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.
