Plasma Transferred Arc (PTA)

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 hardfacing 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

PTA and laser hardfacing powders are available in these standard powder particle size ranges and custom sizes upon request.
