Plasma Transferred Arc (PTA) & Gas Metal Arc (GMAW) Weld Overlays

Paragon FusionClad (PPC) LTD is a leading North American provider of automated weld overlay services to the oil sands, mining and oil and gas industries. Our PTA & GMAW weld overlays provide lasting corrosion resistance and protection.

PTA is an automated high energy, inert gas welding process. It produces the highest quality weld overlay deposits available on the market. The PTA process produces overlays with minimal dilution or deformation of the base material.

PPC services include: Robot Controlled PTA and GMAW weld overlays. Our newly expanded Edmonton shop facilities are conveniently located just off Sherwood Park Freeway and Anthony Henday - close to many Edmonton and Strathcona County fabrication and modularization facilities.
