Plasma Transfer Arc Welding & Cladding Equipment
Patented PTA-PHE Technology
Saint-Gobain Coating Solutions designs and manufactures plasma transfer arc (PTA) welding equipment for hardfacing applications. In fact, our PTA-PHE technology leads the industry in providing a highly cost-effective automated system that protects against abrasion, corrosion, oxidation, friction and thermal wearing.
PHE stands for plasma high efficiency. This technology produces very thin coatings – from 0.5 – 2 mm (0.02 – 0.08”) with high deposit efficiency and deposit speed, as well as low dilution rates. These features combine to save time and money while imparting hard, corrosion resistant single-layer coatings that extend the service life of components in demanding applications.
Compared to other welding processes -- including electrode, TIG & GMAW -- Saint-Gobain’s PTA-PHE system imparts:
- Low dilution:
- Reaching the hardness of the deposited material in a single layer
- Better corrosion resistance
- Low heat affected zone (HAZ)
- Finer dendritic structure:
- Higher abrasion resistance
- Higher hardness
- Deposit close to the final geometry:
- Reduction of the machining time
- Reduction of the machining time
- High deposit efficiency (>95%)
