Coating Technologies in the High Performance Area and 3D Area
Plasma-powder deposition welding or Plasma-Transferred Arc (PTA) welding is a decades-long established coating technology. With OSCAR PLT, we further develop this technology, specifically in the high-performance range of up to 400 A. By implementing two separate powder feeders, considerably higher powder distribution rates can be achieved, and graded powder compositions in the process possible will be feasible. Laser deposition welding enables deposition welding with high-precision energy supply for minor dilution, distortion and residual stress. The developed technology in our facility is based on a coaxial (fully 3D capable) machining head with centric material feed and circular direct diode modules. The head is highly flexibly applicable with wire and powder materials. It has a phenomenal shielding gas flow and powder efficiency.
