Competent partner for laser cladding

Laser welding is the use of high-energy, coherent light on a narrow, precisely defined area which, in comparison to almost all conventional processes, produces almost no penetration, discolouration or structural changes (grain structure, coarse grain, embrittlement) under inert gas.

At high energy input a continuous welding seam is feasible, e.g. for car body sheet welding (automated).

With reduced energy input, the pulsed laser (often used as a mobile device) makes it possible to set individual welding spots or, at a low pulse frequency (typically 0 – 20 Hz), to make critical corrections, e.g. in mould making (also in graining).

For different kinds of materials, such as almost all Fe, Al, Cu alloys as well as Mg or Ti, filler materials are offered as wire (typically from 0.2 mm and upwards). upwards). Different degrees of hardness are available, so that even flat hard applications are possible. Good crack resistance can be achieved through careful selection of additives and welding parameters (e.g. pulse width).

Narrow gaps are required for welding without additional material (small laser spot).

The distortion problems that are characteristic of almost all welding processes are largely eliminated, as the energy input is only high at certain points. Preheating of the workpieces is not necessary (with exceptions e.g. for high degrees of hardness, to avoid crack formation).
