Drawn Arc Stud Welder, AR5100

Artech Welders Pvt Ltd offers a Drawn Arc Stud Welder, AR5100. Drawn arc stud welding is an extremely efficient method of attaching fasteners primarily to mild steel and stainless steel by utilising a constant current DC power supply. In this welding process, a welding rectifier serves as an energy source and provides a continuous welding current. The welding time can be adjusted from 10 to 500 milliseconds. 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. 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. The whole process takes less than one second. During the welding process, a welding fillet is formed around the base of the stud, the dimension of which is predetermined by the ceramic ferrule. The ceramic ferrule concentrates the welding arc and forms a weld fillet around the stud base. Weld gun with shielding gas option can also be used. This method has a higher depth of penetration compared to other stud fielding processes. These machines are most commonly used in transformer manufacturing, ship building industry, boiler industry, power plants, automobile industry, etc.
