Plasma Transferred Arc (PTA)
& Oxy- Acetylene Process
QUALITY, ACCURACY, RELIABILITY AND TECHNOLOGY
“ Our commitment is to provide reliable, cost-effective and most advanced quality Products. “
Our Mission
PTA uses electricity to create an arc which passes between the PTA torch and the workpiece. This arc creates a molten pool on the surface of the parent material to be overlaid. A metal powder is then fed into the molten pool to create a metallurgical bond with the parent material. There is a wide range of powders available for PTA overlay from stainless alloys to tungsten carbides.
PLASMA TRANSFERRED ARC (PTA)
Oxy-acetylene is one of the oldest and most universally used welding processes. In oxy-acetylene welding, oxygen and acetylene gas are combined in a torch handle to produce a flame. This flame in turn melts the metal faces of the two pieces to be welded, causing the liquefied metal to flow between and join them.

PTA Welded Samples
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
