High Speed Reliability

Emhart Teknologies pioneered the concept of using arc welding equipment as a means to fasten components without the need for holes in sheet metal. The system known as The No-Hole Fastening System is comprised of stud welding equipment, the welded stud and a plastic or metal clip that attaches to the stud.

The result is extraordinarily strong attachments that will never be a source of corrosion or fastening system failure. Modular, microprocessor controlled stud welding systems allows customized equipment precisely matched to specific customer requirements.

The Drawn Arc Welding Process

1. The stud is positioned in the gun collet, with the stud protruding slightly from the protective flash shield.
2. Press the stud against the work surface to complete the necessary circuits. Press the trigger to initiate the weld cycle.
3. When the gun solenoid is energized, the stud is withdrawn from the work surface, inducing a pilot arc which cleans both the stud and work surface.
4. The controller automatically releases the main welding current. This weld arc causes a pool of molten metal to form at the base of the stud and on the work surface.
5. The controller then de-energizes the gun solenoid, allowing the stud to plunge back into the molten metal. As the weld pool solidifies, it forms a homogeneous joint.
6. Withdraw the weld gun from the welded stud, and position the next stud in the gun collet.
