Laser hardening and cladding processes at TechnicGroup are carried out in a fully automated manner, using industrial robots. High process parameters repeatability and their control at every stage guarantee top-level quality of the processed surfaces. The mentioned technologies can be used not only for regeneration of worn out or damaged parts of machines and devices, but also for improving the functional properties and extending the working time of new components.
By using the laser cladding technology, we obtain the heat-affected zone in the base material at the level of about 0.5 mm. Compared to conventional methods, laser cladding does not cause the material of the treated element to overheat, thus significantly reducing welding stresses and the risk of post-treatment change in the geometry of the component, as well as adverse structural changes.
What can be seen as a distinctive feature of this process is the possibility of creating layers with special operational properties – we obtain very hard structures, with high abrasion wear, corrosion or creep resistance. Laser cladding process is used for cladding layers of materials with desired properties onto structural steel, low-alloy steel and high-alloy steel elements. Thanks to this process it is possible to obtain cladded surfaces of the best quality of all cladding processes (fine-grained structure without defects). The minimum possible thickness of a single layer is about 0.2 mm. The padding welds can be overlaid in multiple layers, with virtually no limitations, also on surfaces of complex-shaped elements.
Laser cladding is a process in which the source of energy is a concentrated high-power laser beam. The beam is focused on the surface of the base material, it melts the surface only within the laser spot, creating the so-called pool, into which the top layer material is continuously fed in the form of powder or wire. This method ensures a pore-free, impact-resistant and full metallurgical bonding of the overlay materials to the substrate.
