Laser cladding is an interdisciplinary technology utilizing laser technology, computer aided design and manufacturing, sensors & controls and powder metallurgy. Laser cladding utilizes a laser heat source to deposite a thin layer of a desired metal on a moving substrate. The deposited material can be transferred to the substrate by several methods: powder injection, pre-placed powder on the substrate, or by wire feeding. As a cladding process, it exhibits many advantages over plasma cutting and arc welding. These advantages include a reduction in dilution, a reduction in waste due to thermal distortion and a reduction in deposit porosity.
