Scott, I didn't find much on the process that I use, There are many versions available that are good for high volume, such as Plasma, Arc and Gas spray. I have both high volume like a gas Metco P5 and low volume, hand held Gas torch for small individual jobs like a broken ear on a carb or a broken cast iron part big or small, It Is great for repairing freeze cracked blocks and heads. I have repaired Bronze Carbs with good success with bronze powder.
It uses very fine powders. I stock upwards of 30 different cast iron, steel and hard facing alloys, along with many aluminum, copper and bronze Powders. There are hundreds of alloys.
I did find a web site that has good general info (
https://weldguru.com/OLDSITE/spray-welding.html ) but not a lot of detailed technical Info.
I learned 40 years ago from a Metco Field Instructor who had a wealth of knowledge.
It Is not used for GP welding. A good Mig, Tig or Gas welding setup Is a lot more useful for the average or above average welder.
I had a customer who Hired me to weld 2 Chevy 500 CI blocks together to make a V16. That one was very expensive but very cool.
I could send or post pictures if you would like to see the equipment. I could also show the process If that would be helpful.
It has It's applications and Is appropriate for some situations.
If you want to call and talk about this or other subjects, my # Is 585-671-5959 After noon Is best.
Bill
