About Laser Technology
-
Laser cladding is a metal deposition welding process in which a layer of metal powder is deposited on the substrate material. The two materials are then fused by metallurgical bonding through the action of a focused laser beam.
-
Laser hardening is a heat treatment process where a laser beam is focused to heat the surface of a work piece that’s then quenched quickly in open atmosphere.
-
Laser welding is a welding technique used to join multiple pieces of metal through the use of a laser beam without the addition of any external filler material.

The repair of machine parts can be a time and cost saving method in many applications. Laser cladding as a reconditioning process is already frequently used for this purpose. Nevertheless, many critical components, particularly the blades of the low pressure (LP) side of power generating steam turbines, are subject to failure due to severe erosion at the leading edges. Since taking machines offline for maintenance and removal of damaged blade for repair is extremely expensive, increasing the service life of these critical components offers significant economic benefits.
