The ceramic ferrule concentrates the welding arc and forms a weld fillet around the stud base. The whole process takes less than one second.ĭuring the welding process, a welding fillet is formed around the base of the stud, the dimension of which is predetermined by the ceramic ferrule.

Upon completion of the weld time, the gun plunges the stud back to the workpiece, resulting in a permanent bond as the molten material solidifies. When a weld is initiated, current begins to flow through the stud while the weld gun simultaneously lifts the stud to draw an arc, which melts the base of the stud and adjoining surface on the workpiece. The welding time can be adjusted from 10 to 1500 milliseconds. In this welding process, a welding rectifier serves as an energy source and provides a continuous welding current. Arc Stud Welding Machines is an extremely efficient method of attaching fasteners primarily to mild steel and stainless steel by utilizing a constant current DC power supply.
