About the Course

Plasma welding is a wonderful process for welding automation. Plasma torches protect the tungsten, collimate or focus the arc plus allow to use of powdered filler materials rather than just wires. These features make plasma the welding process of choice for overlay and joining in many applications. But it is not widely understood and not taught in depth in schools.

When we build and install plasma welding systems we are asked to teach the process to operators and engineers. I developed this 1-hour class and have presented it to my customers in the US and around the world. We decided to video Plasma University and post it. Watch the class, successfully complete the quiz, and we will send a certificate!
