Capacitor Discharge Stud Welding Process

And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration.

Capacitor discharge stud welding process. Hvac fasteners for heating ventilation and air conditioning if you want to fasten insulation mats in a fast and cost efficient way you should use iso plus cupped head pins. What are the two methods of stud welding. The welding stud is then forced into the melted area and held in place until the metals re solidify. The welding process of cupped head pin welding corresponds with the contact type capacitor discharge drawn arc stud welding cd.

Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. This method can tolerate welding studs to thinner sheet metals than the drawn arc process though it does not achieve welds that are as strong or penetrative. Capacitor discharge stud welding is generally used to weld smaller diameter fasteners to thin base metals. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration.

Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing. The capacitor discharge cd stud welding method. Capacitor discharge stud welding usually cd stud welding for short and arc stud welding. When the weld gun is activated a special precision weld tip initiates a controlled electric arc from the welder capacitor bank which melts the end of the stud and a portion of the base metal.

When triggered the energy discharges as a high current pulse melting the pip to produce an arc. Over the years welding. Capacitor discharge stud welding process energy is stored in a bank of capacitors which are charged to a pre set voltage determined by the type and size of stud and the parent material. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing.

The weld cycle can be completed in 0 01 seconds on material as thin as 0 020 0 5mm. This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10. And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration.
