PTA Presentation

plasma transfrerred arc welding system

Descriptions:

  • 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.
  • 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 of required dimension while others are designed to be a final overlay that protects the work surface.

PTA Units

system consist of Power Source, Water Chiller, Powder Feeder, Oscillator, Welding Positioner, Controller, Column and Boom, Torch.

Summary
:

P.T.A. Deposit shows the following characteristics:

  • 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
  • Reduces Downtime – Parts last longer and fewer shutdowns are required
  • Less Spare Parts Inventory – There is no need to keep numerous spare parts when worn parts can be rebuilt
