the new coating quality

Repair / rework

The special properties of laser cladding enables the repair of shafts, bearing seats, gears, etc. by welding on materials that are similar or of higher quality to the base material. A new, very high-quality coating is achieved.
The low heat input and the associated minimal distortion enable thin-walled and temperature-sensitive components to be repaired. Components that have finished sorfaces or sealing surfaces in some areas can be reworked without any negative impact on these areas.

In contrast to the procurement of new components, the process for reworking individual areas, but also complete components, takes a few days compared to weeks.

The layer thickness to be cladded can be between a few tenths of a millimeter up to well over 20 mm, depending on the material.

The high quality of the cladding material enables the complete rebuilding of threads, keyways, etc.

The very homogeneous and even coating reduces reworking and leads to properties that are often better than those of the new part. This is made possible by a coating composition that is optimally tailored to the application.
A large number of materials are available, starting with soft alloys such as aluminum or bronze, through steel and stainless steel materials, to high-quality non-ferrous materials such as titanium.

Wear protection

Many components are subject to local or global wear and tear. The wear and tear of the material leads to a reduction in usability, a reduction in service life and increased costs.
An alternative to the use of very high-strength and also expensive, difficult-to-machine base materials is the use of a cheaper, easier-to-machine base material in combination with a wear protection layer.

This layer can be welded very locally in the areas in which there is a wear load.
Wear protection layers that are welded on using lasers offer excellent protection and ensure a long component life.

Depending on the filler material used, hardnesses of up to 1000HV can be achieved on average, with high-strength carbides (> 2000HV) providing additional wear protection against abrasion.

The possible layer thicknesses are a few tenths of a millimeter and, with somewhat more ductile materials, several millimeters.

The metallurgical connection with the base material offers optimal adhesion.
Thermal spraying can be used as an alternative for lower requirements or for very hard, but crack-free layers.

Corrosion protection

Are your components used in corrosive media such as salt water, etc.? Laser deposition welding of corrosion protection layers extends the service life and reduces maintenance intervals.

Both iron and nickel and as soon as the base of the powders are used.

In cooperation with our powder suppliers, we are continuously improving the quality and possibilities of laser coatings. In addition to corrosion protection, the focus is on simultaneous wear protection and, of course, workability and costs. The combination with our other processes offers very innovative approaches that offer optimal solutions for the respective applications.


The dimensions of the components to be processed at innojoin are up to 800 mm in diameter and a maximum of 19,000 mm in length and a maximum weight of 6.2 tons.
