Wear-resistant laser cladding

At laser deposition welding with powder, the laser heats the work piece and melts it locally. Simultaneously, an inert gas is mixed with the fine metal powder is added to the process. Operating area supply with the metal/gas mixture takes place via off-axial or coaxial nozzles. The metal powder melts on the heated spot and binds with the work piece metal. The process is applied everywhere expensive components have to be sealed and repaired. In addition to forming tools, engine components and turbine components like blades are considered the most well-known repair parts. The procedure is used with the build up of function layers, like wear protection layer.

Applications
Cladding head YC30 - basic model
Process small batches economically

With brake discs for racing wheels, it is especially advantageous to avoid the thermal warpage with very limited heat input locally. The finely structured, sensitive functional areas are 3D laser hardened.

Milling wear-resistant laser claddings

In the steel industry milling factories, various milling from 0.5 meter to 2 meter lengths is necessary. As the worlds largest steel manufacturer, Tata Steel depends on laser cladding. The wear-resistant cladding extends the service life from just 8 days up to this point in shift operations to more than tenfold that.

Axes for the lumbar industry

The heavy-duty cutting of this axe blade for the lumbar industry have been strengthened locally from wear thanks to new hardnesses and wear-proof function claddings. This drastically saves costs, because repairs are only limited to damaged or used areas. The claddings that are applied with the laser are optionally 0.1 mm and 1.5 mm thick, the width can be adjusted between 1 mm and 5 mm. Thicker coats require applying multiple layers on top of one another.
