Laser Cladding is a process in which a highly concentrated laser beam is used as a heat source to create a pool on the base material onto which a filler material or powder is directly fed into the pool via special nozzles. The powder/filler is being heated by introducing it in the same laser heat source onto the required base material to form a metallurgically bonded layer of coating.
The main advantages of the system against arc welding methods are lower heat distortion, reduced dilution (typically <4%), lower porosity (<1%), better surface uniformity and negligible heat affected zone (HAZ). Additionally, subject properties practically eliminate the need for post-processing and its associated time and costs.
With the diode laser cladding technique, cracking and de-lamination that often follows the arc welding is practically eliminated.
Laser cladding uses a metallurgical bond between the base material and the substrate, unlike a thermal spray process where the bond is mechanical.
