Consistent results with laser cladding

With laser cladding, which is also known as laser metal deposition, metal powder is fed into a melt pool generated by a laser beam. The melted material is deposited accurately and with minimal heat to the underlying substrate.

Laser cladding enables a metallurgical bonding with the base material substrate, like in case of PTA surface 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 once the parameters are fixed for a certain design, the final results are consistent for all parts.

The laser cladding process is used to improve wear resistance and to repair worn or damaged surfaces. It is a flexible process since it is possible to mix two or more powders at the same time as the feed rate is separately controlled for both feed streams. 

Typical working range

• Deposition rate: up to 8 kg/hour
• Deposition thickness: 0.5 - >4 mm
• Deposition hardness*: >22 - 61 HRC

* Typical for PTA welding / 5% -10% higher with laser cladding

 Benefits

• Suitable for automation
• No fusing required
• 0.5->4 mm thickness
