Plasma Transferred Arc Welding

At ASB-Hannecard, we offer industry-leading Plasma Transferred Arc Welding services. This advanced welding process is used to provide industrial parts and components with exceptional corrosion and wear resistance. Our PTA welding services help customers in demanding industrial sectors extend the lifespan of components and equipment.

What is PTA Welding?

The Plasma Transferred Process (PTA) uses a highly focused plasma arc to deposit material and fuse it to a substrate. The heat from the plasma creates 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 most common materials used to provide both wear and corrosion-resistant surfaces with unsurpassed microstructures. After the material is deposited and bonded to the substrate, it cools and solidifies, resulting in a dense protective coating.

Advantages of Plasma Arc Welding

• Provides excellent wear and corrosion resistance
• Results in smooth deposits, reducing the amount of post-weld machining required
• High precision and control over weld parameters
• Automated set-ups and repeatability
• Weld deposits have very low levels of oxides, inclusions, and discontinuities
• Allows for a smaller heat-affected zone and faster welding speeds than other methods

What is the Purpose of PTA Plasma Welding?

PTA is used in applications where extreme wear resistance is essential. Plasma-transferred arc coatings are used in a variety of industrial applications, ranging 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. By providing a dense, uniform finish, PTA welding significantly extends the service life of components. Its ability to improve material durability in extreme environments makes it a cost-effective solution for reducing maintenance requirements.

Common Industrial Applications for PTA Plasma Welding

Industries that use PTA welding include aerospace, oil & gas, automotive manufacturing, mining, agriculture, and steel processing. Specific components that benefit from PTA plasma welding include:

• Cutting Tools
• Dies
• Drilling Tools
• Pumps
• Valve Stems
• And more
