Powders for Plasma Transferred Arc (PTA)
Plasma Transferred Arc (PTA) Welding
| Process Heat Source | High Energy Plasma Transferred Arc |
| Process | The High-Energy Plasma Transferred Arc melts the surface of the base material while simultaneously introducing metal powder into the arc, where it is also melted. As the materials solidify, a metallurgical bond forms between the filler and the base material. |
| Typical Process Characteristics | Deposition Efficiency: 2-12 kg/hour, Suitable for automation |
| Characteristics | Plasma Transferred Arc (PTA) surface welding is a thermal coating technique designed to enhance the wear and corrosion resistance of metallic surfaces. |
| Appliocation | It can be applied to various components in multi industries, such as oil and gas, energy sectors, and automotive. |
| Besides, it is suitable for high-volume automated applications, such as automotive engine valve coatings. The process features low substrate dilution and is compatible with a wide range of materials. |
