"PTA" is an acronym for Plasma Transferred Arc Welding. As the name suggests, it is a welding method that uses a plasma arc for melting metals, and it utilizes powder as the welding material. Due to the characteristics of the PTA welding method, it is possible to perform overlay welding of superalloys such as Co-based alloys represented by Stellite, which are resistant to heat and wear, as well as Ni-based superalloys that are highly resistant to corrosion and heat. Additionally, overlay welding of wear-resistant alloys containing ultra-hard carbides like NbC can also be performed. **Features of PTA Welding** - Special welding materials that cannot be formed into wires or rods can be used in powder form. - By powdering the welding material, welding of composite alloys containing carbides can be easily carried out. - Thin overlays and internal diameter overlays that conform to shapes can also be applied. *For more details, please refer to the related link page or feel free to contact us.*
