Laser Cladding Alloy Powder

With the significant advances made in laser technology, laser cladding has gained increasing acceptance. Compared to the traditional overlaying processes, it has the advantage of low distortion, low dilution, near net shape after cladding, and fine microstructure for superior properties. However, because of concentration of heat, it could cause stress cracking. Based on our understanding of the laser cladding process, we had developed a family of powders especially for laser cladding. Our customers have endorsed them unanimously.
