Characteristics of laser cladding
Laser cladding is the technology for wear resistant hardfacing of the future. A metallic powder or wire is molten in the laser beam and deposited onto a metal substate. The nozzle system can either be co-axial or lateral. The laser beam has two funtions, preheating the substrate and melting the metal powder or wire.This way a perfect metallurgical bond between substrate and deposit is assured.

Advantages of laser cladding
- automatic CNC process
- deposit thickness 0,3-2 mm/layer
- high precision in the deposit layer: tolerances 0,1 mm
- perfect metallurgical bonding, no risk for debonding
- no porosity, high density of the deposit
- no cracks
- delution with the substrate: less than 1 %, so the optimal characteristics of the deposit are assured on the whole thickness
- heat-affected zone (HAZ) reduced and virtually no deformation
- a wide range of deposit metals
