Thermal Spray Weld Services

Thermal spray weld technology through a twin wire arc process can extend the life of your machinery components for that extra runtime. When standard repair processes are unable to gain that extra 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.

How Does Thermal Spray Weld Work?

The process uses a pair of continually fed wires which are 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 specification measurements.

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

The EuTronic Arc Spray 4HF unit provides the functionality and versatility to apply spray weld to the most visible areas. This system delivers a high-quality coating while providing the technician with full control over deposit application and thicknesses.
