Laser powder cladding



Repair and cladding with powder

ALOpowder laser cladding is a manufacturing process in which the laser beam melts a base material on the surface and a pulverised filler material is injected into the weld pool via a nozzle.

Due to the lower energy input compared to conventional arc welding processes, the components experience less distortion and minimal changes in the microstructure.


  • Deposition of wear protection coatings
  • Repair of components
  • Simple modification of the component geometry
  • Additive manufacturing

Technology for all shapes

Processing optics

Depending on the function and application of the component, various processing optics ensure optimum surface processing.


with fixed laser track width

ALOpowder is a processing optic for laser powder cladding with a fixed laser track width. Its compact design ensures very good accessibility during the cladding process.

Area of application: cladding of 3D surfaces as corrosion and wear protection, repair of worn components, design modification or correction of production errors and additive manufacturing of 3D components.


with variable laser track width

The ALOpowderzoom processing optics guarantee maximum flexibility for welding applications thanks to the variable laser track width.

Area of application: Corrosion and wear protection, repair, design modification and additive manufacturing, especially for large components such as shafts or bearing shells with higher productivity.

internal coating optics

The internal coating optics for laser powder cladding guarantee you accessibility for processing internal surfaces.

Area of application: Cladding of internal surfaces, blind bores, pipes and cylinders, repair of worn contours as well as corrosion and wear protection.

Applications with ALOpowder

Laser cladding is used to apply wear protection coatings to highly stressed component surfaces. It is also used to repair components or to quickly and easily change component geometries in machine, tool and mould making as well as for the additive manufacturing of 3D components.

Your cost advantage:

Cladding directly on site.

We offer laser processing using ALOpowder laser cladding as well as ALOhard laser hardening directly on the component premises.

This eliminates transport and set-up times for the component as well as the associated costs and risks.
