Drawn arc stud welding is a highly efficient method of attaching fasteners primarily to mild steel and stainless steel by utilizing a constant current DC power supply. The process uses a welding rectifier which serves as an energy source and provides continuous welding current. The welding time can be adjusted from 10 to 600 milliseconds.

Process

During welding current begins to flow through the stud while the weld gun simultaneously lifts the stud to draw an arc that melts the base of the stud and adjoining workpiece surface. Upon completion of the weld time, the gun plunges the stud back to the workpiece, resulting in a permanent bond as molten material solidifies under concentrated welding arc induced by ceramic ferrule around stud base.

Advantages

  • Excellent reliability and uniform quality
  • Requires no flux or filler
  • High duty cycle
  • Eliminates need fo drilling and riveting

Features

  • Password Protection
  • Alpha-numeric text display
  • Fine adjustment of weld time and weld counter
  • Protection against overloading of machine

What are the Dos and Don’ts for Projection Welding?

Projection Welding is a widely used type of resistance welding. In this type of welding, multiple projections can be welded on the workpiece. These projections can be circular, round dimples, extended corners, rib type, or elongated ridges of weld nuts. The advantages of projection welding include better uniformity and appearance of the weld. Multiple projection […]
