Sajmu Technologies is the name to turn for innovative technology. With Plasma Transferred Arc Welding we provide high productivity, high quality of powder deposits with minimum powder loss. Our advanced technology ensures significant lower cost for hardfacing , surfacing and cladding even in the most challenging area.
We are the manufacturer, supplier and exporter of Plasma Transferred Arc– PTA welding machine.
Plasma Transferred Arc (PTA) System is a high energy, inert gas welding process.
Argon 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.
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 of required dimension while others are designed to be a final overlay that protects the work surface.
