Plasma Transferred Arc (PTA) weld is a high-energy, low heat welding process that provides minimal interaction with the base material while allowing the application of a thick weld overlay. Commonly applied overlay includes tungsten carbide, chrome carbide, and titanium carbide.

CIM has developed proprietary PTA TungTough™ and TungHard™ WCO. The ideal combinations of high hardness, superior wear resistance and toughness make them the preferred materials for extreme wear applications.
