Plasma Transferred Arc Welding (PTAW): Advanced Surface Enhancement Solutions
Plasma Transferred Arc Welding (PTAW) is an advanced hardfacing technology derived from Gas Tungsten Arc Welding (GTAW). By integrating plasma arc principles, PTAW offers superior control, higher energy density, and enhanced metallurgical performance compared with conventional welding methods.
At FNS Pipeline Technology Co., Ltd., PTAW is widely applied to improve the surface performance of critical equipment components, delivering exceptional wear resistance, corrosion protection, and extended service life for demanding industrial applications.

What Is Plasma Transferred Arc Welding?
PTAW uses a constricted, high-energy plasma arc to create a stable molten pool on the base material. Alloy powders are injected directly into this plasma arc, where they are fully melted and metallurgically bonded to the substrate.
Unlike traditional welding or thermal spraying processes, PTAW produces a dense, low-dilution hardfacing layer with excellent fusion quality, ensuring superior mechanical integrity and long-term reliability.
PTAW Process and Material Capabilities
The PTA welding process enables precise deposition of superalloy metal powders, including:
- Carbide-reinforced composite alloys
- Medium- to high-hardness wear-resistant alloys
- Corrosion-resistant alloys
- Tough, impact-resistant materials
This flexibility allows FNS to tailor hardfacing solutions to specific service conditions, significantly improving:
- Mechanical strength
- Abrasion resistance
- Corrosion resistance
- Component lifespan
- Maintenance efficiency
By reducing repair frequency and downtime, PTAW helps customers achieve higher productivity and lower total operating costs.
Key Advantages of PTAW Technology
Compared with TIG, MIG, and conventional hardfacing methods, Plasma Transferred Arc Welding offers several distinct benefits:
- Superior alloy performance with higher strength and corrosion resistance
- Low dilution rate, ensuring optimal alloy chemistry and coating integrity
- Excellent metallurgical uniformity, delivering consistent, repeatable results
- Minimal filler material loss, improving material efficiency and cost control
- Economical refurbishment, extending component life without full replacement
These advantages make PTAW an ideal solution for precision hardfacing and high-value component restoration.
