In 1945, the first Wall Colmonoy Spraywelder™ unit was manufactured and the “COLMONOY SPRAYWELD™ PROCESS” was invented!
The Sprayweld™ Process has successfully coated a wide range of products in many industries leading to extended service life, reduced maintenance and downtime – all leading to significant cost savings. Press and Blow plungers, pump shafts and valve shafts are just a few examples of products using this process. Industries include glass container manufacturing, chemical, petroleum, automotive and plastics and many others.
Wall Colmonoy nickel-based alloys along with the Spraywelder™ are the industry’s leading process to rebuild surfaces and provide wear protection.
The Spraywelder™ System offers tight spray patterns and high spray rates to produce dense, low-porosity overlays. The Model J-3 is the culmination of more than 65 years of technical innovation following the invention of our first thermal spray gun.
The Sprayweld™ Process offers numerous advantages that favor its use in many applications:
In the Sprayweld™ Process, a powdered alloy is thermal sprayed onto a part and subsequently fused to the base metal by a heat source. This creates a smooth, nonporous, metallurgically bonded overlay, producing a fused coating within 0.25 mm (0.01”) of the required finished dimension.
J-3 SPRAYWELDER™ SYSTEM
Up to 19 lbs/hr with standard model, and 30 lbs/hr with high-output unit.
Flame energy of up to 92,000 BTUs and increased target efficiency deliver hot metal spray particles to the base metal. The final result is a strong, dense overlay.
The Spraywelder is designed from our vast field experience and built for years of daily use.
