PTA Hardfacing

Plasma Transferred Arc Welding controls all welding parameters creating a repeatable process. We have both fully automated robotic machines offering high production parts with quick and precise overlay in both corrosion and erosion resistant weld powders. We have 15 PTA machines, 3 of which are fully automated.


This liquid QPQ nitriding process produces a thin high hardness case with no deformation of the base. This process is used against wear and corrosion and will reach a case depth up to 0.005” thick.


Manluk’s cladding capabilities include 8 Cladding machines capable of cladding many different industry approved overlay procedures. From 1.5” ID through to almost unlimited size, weight and configuration.

10 automated hot wire pulse TIG machines. 2 machines that have oval capabilities.Massive stress relieve capabilities. 3 large pwht ovens.
