Laser Cladding Process

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

A stream of a desired 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 just where it is required.

Process Advantages

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