Plasma Transferred Arc Welding (PTA) Hardfacing

PTA Hardfacing

PTA cladding is a coating method to apply a wear-resistant and/or corrosion-resistant material to a part. PTA is an abbreviation for Plasma Transferred Arc. This name is derived from how the material is transported by plasma. The powdered material is added to the welding arc, allowing it to melt.

Tungsten Inert Gas (TIG) Hardfacing

Weld overlay, also known as weld cladding, is the process of melting a protective layer of metal atop another metal surface. The application of laser light heats and melts the cladding metal onto the parent metal, creating a welded surface with greater corrosion or wear resistance.

Cladding (Hot Wire TIG)

Cladding using the tungsten inert gas (TIG), also known as the gas tungsten arc welding (GTAW) process, in conjunction with a mechanized system is a common way to improve the corrosion resistance or wear resistance of tools.
