Laser Powder Deposition Welding

A wear resistant coating for your components!

While performing laser powder deposition welding, the component surface is slightly melted by the beam, then a gas stream injects filler metal in the form of powder into the bath. This process generates a metallurgically bonded layer with least possible dilution with the base material (less than 5%), free of pores and cracks.

Compared to conventional methods (TIG/MAG), laser powder deposition welding manages without larger amounts of heat, thus reducing warp, and ensures a homogenous seam structure. The optimized reproducibility is a huge advantage for serial production.

Thanks to our wear resistant coatings, lifetime of your components or tools can considerably be increased and even -by appropriate selection of filler material- improved with respect to their properties.

Laser powder deposition welding proves to be ideal for modification of components by wear resistant coatings and repair of damaged or worn components. In either case, the lifetime of the object is extended at once.

Benefits

This technology is characterized by high process speed, simultaneously by low heat input and minimum deformation.

Outstanding process speed
Operating efficiency for large areas
Low mixture with base material (less than 5%)
Reduced warping thanks to low thermal input
Excellent accuracy and reproducibility (serial production)
Large possibilities for base and filler materials to be combined
Homogenous surface structure, not difficult to machine

No dataset available for your component?
No problem!

Our AL-ROCK machine is equipped with a scan system to capture the contours to be processed. These data are quickly evaluated to compose an efficient procedure according to your specifications.

Repair instead of scrap yard

A second life for your components!

Laser powder deposition welding is a fully developed and proven industrial alternative to disposal:

This way we can repair your components, improve the properties of surfaces or apply and implement geometrical modifications. In any case, the lifetime of the components is extended.

Smaller and even larger damages can be eliminated quickly and nearly without a trace. The component or tool in question will ready to be used again. Design changes are possible likewise.

Take advantage of laser powder deposition welding to improve the surface of components by wear resistant coatings or to repair worn or damaged items. For creation of proper alloys matching best the intended application, we dispose of a double powder conveyor.

Already in the construction phase of an object, keep this method in mind: Use a cheap material for base material, and apply wear-resistant coating by means of our service.

Mobile on site:

Our AL-ROCK

Thanks to our „AL-Rock“ machine, we became a pioneer for offering the mobile service of laser hardening and laser powder deposition welding directly on site. Our robot features a crawler chassis, ready to move directly to the place of action.

In many situations already, we were able to assist the clientele, when urgent deadlines had to be met. We are proud, that we could help them securing competitive advantages.
