Did you know that there are several differences between PTA welding and regular welding? PTA, which stands for Plasma Transferred Arc, is a continuous welding process that melts both base and additive materials with minimal heat impact. The arc in PTA welding is both efficient and thin, which results in very clean, high-quality welds, while the mixing of the base material is minimal. Thanks to the high performance, materials that are otherwise difficult to weld can also be coated with good results.
– Advantages of the PTA process are structural quality, metallurgical homogeneity and controlled penetration, says Lennart Zetterlund, operator and PTA expert.
