Laser cladding is a method of fusing a cladding material together with a thin layer of a substrate surface by adding the cladding material to the substrate surface and using a laser beam of high energy density. The cladding material is mostly in the form of powder or wire, with powder cladding materials being most commonly used. For most parts to be clad, the position to be clad is on the outer side of the part, while for other parts to be clad, the position to be clad is on the inner side of the part, and the cladding head needs to enter the part and fuse the cladding material on the inner wall of the part.
