Thermal Spray Weld Services in Edmonton

Through a twin wire arc process, thermal spray weld technology can extend your machinery components' life and provide extra runtime. When standard repair processes cannot gain that additional life due to physical gouges, severe undersize measurements, or a combination of the two, thermal spray weld may be the answer! Achieve that extra component life for your heavy-duty machines with our thermal spray weld services at TRAC Engine Services Ltd in Edmonton.


The thermal spray weld process uses a pair of continually fed wires melted by an electric arc when the wires make contact. The molten droplet material is atomized by compressed gas and propelled towards the workpiece substrate to form a durable coating. The coating application and thickness are monitored and applied as needed for each specific area on the workpiece resulting in precise modifications.


Once the coating application is completed, our trained technicians apply a final machining process to bring the component back within OEM specification measurements and surface finish.

Thermal Spray Weld Benefits

  • No thermal distortion

  • No metallurgical alteration of the substrate material

  • Low pre-heating requirements

  • Low heat input during spraying

  • Variation of coating thickness across the surface

  • High bond strengths

  • Good for the dimensional restoration of the component

  • Coating thickness available up to 0.040”

  • Finish machining restores the component back to spec measurements

Typical Applications

  • Pump and compressor shafts

  • Engine block mains

  • Engine block cam mains

The Equipment
