Plasma Transferred Arc (PTA) Welding
QUALITY, ACCURACY, RELIABILITY AND TECHNOLOGY
Arcraft is the name to turn to for innovative technology With Plasma Transferred Arc Welding we provide high productivity,
high quality of powder deposits and significantly lower cost for hardfacing even in the most challenging area such as valves, valves seat of internal combustion engine, accessories for ship, petroleum and power generation
PTA is also used for reclamation of worn jobs extending the life of components and giving a huge savings on cost
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

Applications
Reduces Cost - Restoring a worn part to "as new" condition generally costs between 20-70% of a brand new replacement part
Prolongs Equipment Life - Service life increases of 3 to 10 times are common with properly overlaid parts
High Quality Deposit - It produces a very high quality deposit offering optimal protection with minimal dilution or deformation of the base material
Precise Coating - 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
Protection - Corrosion, thermal shock and abrasion Metal buildup / Reclamation
