Powder Plasma Transferred Arc Welding

In powder plasma welding, you melt the supplied metal powder in the plasma arc and deposit it as a layer on the component. The powder is fed into the plasma jet via a carrier gas. You have to make sure that the powder feed rate and travel speed are properly matched, otherwise you'll get an uneven or too thin layer. The powder must be dry and free of contaminants, and you should keep an eye on the process to ensure the deposit is uniform.
