A new repair system for hardfacing of parts in metallurgical industries has been developed. The system can produce single pass quenching or cladding width of 10 - 35 mm, thickness of 0.5 - 10 mm. The wide range of powder materials can be deposited to provide hardfacing layers against wear, corrosion and oxidation. Comparing with welding and flame spraying, it presents clear advantages with low distortion, low dilution, low cost and small postclad machining. It has been successfully used to repair some of parts, for example, roll, drawing wire wheel in high speed wire, and so on.
