NEW PROCESS COMBINES PLASMA WITH GMA WELDING

A process of gas metal-arc welding in a thermally ionized gas is described in which the filler metal is fed along the axis of a plasma stream to the workpiece. Two of the most important electrode arrangements that can be employed with this process are discussed. The electrical properties and the flexibility of gas metal-arc and plasma-GMA welding are compared. Data on deposition rate, welding, speed, penetration and wetting-in are determined. Finally, a number of possible applications and some already achieved are described.
