Drawn Arc Stud Welding

Drawn arc stud welding is a process by which a metal stud is joined to a metal workpiece by heating both parts with an arc. It permits strong, one-sided welds on base metals with thicknesses starting at 0.048″ (1.2 mm), and produces welds in as little as 0.06 seconds. During the process, the stud is loaded into the stud weld tool chuck, and a ferrule is placed over the end. Then, the weld tool is placed against the work position. When the trigger is pressed, the DC power supply sends a signal that energizes the weld tool’s internal lift mechanism lifting the stud, drawing the pilot arc. A key factor that differentiates stud welding from other fastening processes is that the fastener is attached to the workpiece without marring the other side. This method provides highly reliable fastening for a wide variety of applications and allows almost any size or configuration of a metal stud to be welded quickly to a workpiece, while providing maximum weld penetration and reliability. Drawn Arc Advantages Drawn Arc Applications

Drawn arc stud welding provides excellent welding success under a broad range of conditions. It produces a full cross-sectional weld, forming a bond that is stronger than the surrounding metal. This section examines its quality, productivity, and cost advantages, including: improved weld strength; aesthetic appeal; ample design freedom; faster, easier manufacturing with fewer steps; labor savings; and, fabrication savings. A weld produced by the drawn arc process offers a variety of benefits, including high structural integrity, excellent productivity, leak resistance, corrosion resistance, as well as creating a joint that is less susceptible to loosen from noise and vibration.
