PLASMA TRANSFERRED ARC (PTA)
Plasma Transferred Arc (PTA) is an advanced fusion welding technology used for hardfacing superalloys or mechanical components exposed to corrosion.
This method enables the application of exceptionally wear-resistant tungsten carbide coatings, even in significant thicknesses. By ensuring excellent adhesion to the material surface, it can extend the service life of components by up to 10 times.
In boiler systems, coil tubes are coated on their outer surfaces using the PTA process to protect them against erosion caused by ash. Thanks to the automation systems we have developed, specific sections of these tubes can be coated across a full 360° range, ensuring maximum durability.
ADVANTAGES OF PTA
Durability and Efficiency
It forms a strong bond with the surface at high temperatures, providing homogeneous, long-lasting, and wear-resistant coatings.
Cost and Sectoral Alignment
Material loss is minimal; it reduces costs by minimizing unplanned downtime and is widely used in heavy industries such as energy, petrochemicals, and mining.
Flexibility & Implementation
It can work with various alloy powders and, by being integrated into automation systems, can be applied with precise thicknesses in specific, targeted areas.
