PTA Welding Powders
The PTA (Plasma Transferred Arc) process welds a metallic coating material in powder form to a substrate to produce a hard, wear-resistant coating that is metallurgically bonded to the substrate. The powder is injected into the stream of plasma gas, depositing it onto the workpiece. Wirh PTA process the dilution with the substrate can be controlled as low as 5%.
