Surface coating method in which two wires are melted by an electric arc and ejected by compressed air. Beskrivning The process Two metal wires [1] are fed through the gun, and meet at its opening. A connected power supply creates an arc between the live wires, which means that it melt. Compressed air [2] which is supplied through the center of the gun is focused on the arc which pulverizes molten material and ejects it at the workpiece that is coated. Sometimes an additional air stream [3] for enclosing the beam is used. Wire arc spray coating Process photos Process films
