Plasma Transferred Arc
PTA is a high energy, low heat inert gas weld overlay process that provides minimal interaction with the substrate material while allowing application of very thick coatings, often up to 3/8”. Commonly applied coatings include tungsten carbide, chrome carbide, Stellite and stainless steels.
Features and Benefits
Low heat input
Small heat affected zone (<0.150”)
Low dilution, typically 2% – 5%
Metallurgical bond increases adhesion of the overlay to the base material
Wide variety of materials can be applied
Minimal distortion of the substrate
