Hot Wire Laser Deposition Welding on Your Component
At OSCAR PLT, we have developed a coaxial direct-diode laser processing head for the shaping laser deposition welding. The coaxial construction with its central material feed enables high-quality shape generation in all positions independently of direction. By that means, the process can be easily and quickly converted from the frequently used powder materials (high volume deposition rate and stable process) to wire-shaped filler materials (high surface quality and material efficiency).
Highest volume deposition rates and resource efficiency are achieved through hot wire laser deposition welding. The robust system has brilliant shielding gas coverage and powder efficiency.
3D Shaping with Various Materials
3D Manufacturing or additive manufacturing has the potential to revolutionise current construction rules and manufacturing processes. The rules and processes enable components with a completely new design, functionality, materials, material combinations and individualisation. We deal with generative manufacturing using deposition welding technology. Unlike the powder-bed based generative technologies, by using the laser deposition welding, a “real 3D shaping” in different spatial directions of the component coordinate system can be carried out by pivoting and turning the process head or the workpiece. Simultaneously, considerably higher buildup rates can be achieved, partly also with different materials on one component.
