Plasma Transferred Arc (PTA) Weld Deposition  

The PTA process is easily automated, providing a high degree of reproducibility of the weld overlays. In addition, because of the highly concentrated heat source, this process benefits from high powder utilization and can achieve a very low level of iron dilution in the overlay.

Because the hard facing materials are in powder form, it is possible to produce overlays from many different materials and combinations of materials with a wide range of hardness and other properties.


  • Automized, semi automized and manual solutions possible.
  • Wide range of base materials and consumables are workable.
  • High deposition rates, low powder losses.
