What is plasma transferred arc welding?

The Plasma Transferred Process (PTA) gives a metallurgical bond to the substrate by transferring the arc during the feeding of the chosen powder chemistry. Cobalt, Carbides and Stainless materials are the typical materials used to give both wear and corrosion resistant surfaces with unsurpassed microstructures.
PTA takes place where severe wear-resistance is vital. Applications for plasma transferred arc coatings range from direct impact cutting tools in the mining industries to highly erosive and corrosive conditions in a molten metal bath, such as rotating bearing components in hot dip galvanizing.
Some Advantages of Plasma Arc Welding:
Finish product has smoother deposits, shortening the amount of post-weld machining required
Equipment has a lot control over weld parameters
Automated set-ups
Weld deposits have low levels of oxides, inclusions, and discontinuities
Understanding equipment and part working conditions as well as part geometries and base material chemistries are very vital in establishing process specifications. The gravity powder feed system in the automated process area has both vertical and horizontal positioning and drive systems to apply an evenly layered surface.
