PTA Hardfacing And Cladding Machine |
 |
(PTA) 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.
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.

Plasma Welding |
 |
- Less sensitivity to changes in Arc length.
- Recessed electrode reduces the possibility of tungsten inclusions in the weld and can substantially increase the period between electrode dressings resulting in increased life.
- Weld in a single pass up to 6 mm plates in square butt position and 10 mm plates in only two passes.
- Keyhole mode of welding gives smaller heat affected zone resulting in reduced strength loss at the joint for heat treated metals, promotes less grain growth which gives better ductility.
-Reduced weld time results in less embrittlement by carbides and complex intermetallic compounds for stainless steel and super alloys.
- Equalization of distortion stresses results in less residual stress.
- Less filler metal required in keyhole mode significantly reduces porosity.
- Plasma arc welding (PAW) is a advanced version of the tungsten inert gas (TIG) welding process. |
