Specifications

PTA welding equipment for reclamation, hard facing and repair.

Process:

Plasma Transferred Arc is used for welding at high arc travel speeds. For initiating a transferred arc, a current limiting resistor is put in the circuit, which permits a flow of about 50 amps, between the nozzle and electrode and a pilot arc is established between the electrode and the nozzle. As the pilot arc touches the job main current starts flowing between electrode and job, thus igniting the transferred arc. The pilot arc initiating unit gets disconnected and pilot arc extinguishes as soon as the arc between the electrode and the job is started. This process provides minimal dilution and high resistance to chipping because of its dense metallurgical structure, free of voids, oxide films, and discontinuities. Used on parts subject to corrosion, thermal shock, severe abrasion, slurry erosion, or extreme impact forces to increase component life.

Features:

• 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.
• 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- Certain alloys are made to rebuild a part to a required dimension while others are designed to be a final overlay that protects the work surface.
