PTA Job Work

Plasma Transferred Arc System (PTA) is a high energy, inert gas welding process. Ar is basically used for arc plasma supply, powder transport and molten material shielding. It produces a very high quality deposit offering optimal protection with minimal dilution or deformation of the base material. It is a process that deposits very precise coatings of perfectly controlled alloys on mechanical parts that are subject to intense wear; significantly extending their service life.PTA technology is particularly effective in protection against corrosion, thermal shock and abrasion. A wide range of overlay alloys is available for practically any part. Some alloys are very hard, others are softer with hard abrasion-resistant particles dispersed in a matrix. Certain alloys are made to rebuild a part to a required dimension while others are designed to be a final overlay that protects the work surface.
