Laser cladding

Laser cladding is a process in which a surface is applied to a workpiece by means of spot melting and simultaneous application of almost any material. This is done in powder form, e.g. as metal powder. In laser cladding, the laser heats the workpiece selectively and melts it locally. At the same time, an inert gas mixed with fine metal powder is fed in. The metal powder melts at the heated spot and bonds with the metal of the workpiece. There is little mixing of the base material.

The laser cladding process is fully automated and is monitored only by a system operator.
