At Heavy Equipment Repair we perform a variety of specialty welding processes, all geared towards protecting your Oil Sands and Mining equipment. Our cladding will help improve your equipment’s mechanical strength in addition to increasing its wear, galling, and corrosion resistance.

We are proud to offer the following specialized welding processes:

Plasma Transferred Arc Welding

The PTA Process

Plasma Transferred Arc is the thermal process for applying corrosion and wear resistant layers to metallic materials. During the PTA process, soft alloys, medium and high hardness materials and carbide composites are deposited on to a variety of base materials. These high-quality metallurgically fused deposits are used to improve mechanical strength, wear resistance, galling resistance and corrosion resistance on relatively low-cost surfaces.

Advantages of Plasma Transferred Arc Welding

• Easily automated
• Wide range of base materials and consumables can be utilized
• High metallic powder feed deposition rates and low powder losses
• Produces alloy deposits that are tougher and more corrosion resistant than other welding processes

Weld Overlays

Weld Overlay (WOL), also known as cladding, hard-facing, weld-cladding, or weld overlay cladding, is a process where one or more metals are joined together via welding to the surface of a base metal. At Heavy Equipment Repair, we use alloys formulated with both tungsten carbide and chromium carbide to ensure you get the maximum life from your equipment.

B-Pressure Welding

At Heavy Equipment Repair, we have several B-Pressure Welders, each certified to work with boilers, pressure vessels, and pressure piping systems.
