Capacitor Discharge Stud Welding Process

The weld cycle can be completed in 0 01 seconds on material as thin as 0 020 0 5mm.

Capacitor discharge stud welding process.

Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. When triggered the energy discharges as a high current pulse melting the pip to produce an arc. The welding stud is then forced into the melted area and held in place until the metals re solidify.

Capacitor discharge cd stud welding using very short weld times permits the welding of small diameter studs to thin lightweight materials. Short cycle stud welding is a faster form of drawn arc stud welding which can use capacitor discharge weld studs instead of drawn arc studs. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing.

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. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing. 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.

Over the years welding. The capacitor discharge cd stud welding method. What are the two methods of stud welding. Capacitor discharge stud welding is generally used to weld smaller diameter fasteners to thin base metals.

And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration. Capacitor discharge stud welding usually cd stud welding for short and arc stud welding. The welding process of cupped head pin welding corresponds with the contact type capacitor discharge drawn arc stud welding cd. 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 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.
