Laser Cladding or Laser Deposition is a processing technique used for adding one material to the surface of another in a controlled manner.

Laser cladding is a surface welding method that enables a metallurgical bonding with the base material substrate, like in case of PTA suface welding.The overlays can be applied to most Fe and Ni based substrates with some exceptions.

A high energy laser beam creates an intense heat input and thus alloys are bonded to the surface with a low degree of dilution (<5%). Laser cladding can be fully automated and thus once the parameters are fixed for a certain design, consistent final results are achieved for all parts.

A stream of a desired metallic powder is fed into a focused laser beam as it is scanned across the target surface, leaving behind a deposited coating of the chosen material.

This enables the applied material to be deposited selectively, accurately and with minimal heat input just where it is required.

1. Additional material can be placed precisely where desired.
2. A very wide choice of different materials can be both deposited and deposited onto.
3. Deposits are fully fused to the substrate with little or no porosity.
4. Minimal heat input results in narrow HAZ (heat affected zone).
5. Minimal heat input also results in limited distortion of the substrate and reduces the need for additional corrective machining.
6. Easy to automate and integrate into CAD/CAM and CNC production environments.
