DA Stud Welding
Drawn Arc stud welding (also known as DA stud welding) achieves very strong penetrative welds on materials of 2mm thickness and above. DA products are really the only choice for stud welding large diameters and they can tolerate surface curvature and imperfections such as light rust, grease, and scale. The Drawn Arc stud welding process provides a supremely neat and controlled weld fillet and is suited to multi-gun applications.
DA Welding Process
The Drawn Arc stud welding process involves setting current and weld time, lifting a stud to a pre-set height, then using the pilot arc the lifting causes to create a molten pool in the plate. Return spring force then forges the stud into the molten pool; the process requires a ferrule to contain the molten metal and shape the fillet.

What is Drawn Arc Welding?
Drawn arc stud welding is one method of stud welding which creates a lasting weld to a piece of material on a single side. Drawn arc is suited for welding onto thick materials (2mm+), curved surface materials and for large diameter applications. (Unlike the alternative welding option, capacitor discharge which is suitable for thinner materials and those without surface imperfections such as light rust or grease.)
Drawn arc stud welding doesn’t penetrate the materials and therefore creates a single-sided fastening that doesn’t risk leaks or weakening of the material and is extremely long lasting.
- Based on the diameter to be welded, the current and weld time is set on your drawn arc stud welding machine. The DA stud is then placed on the plate.
- The stud welding machine triggers a pilot arc and the stud lifts to a pre-set height.
- The main arc process then melts the weld end of the stud, creating a molten pool of metal in the plate.
- Return spring pressure forges the stud into the molten pool, welding it to the material. The ferrule contains the molten metal and shapes the fillet. It results in an extremely strong bond between stud and material.
