Capacitor Discharge Stud Welding Process

Capacitor discharge stud welding is generally used to weld smaller diameter fasteners to thin base metals.

Capacitor discharge stud welding process.

Capacitor discharge stud welding usually cd stud welding for short and arc stud welding. And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration. And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration. The welding stud is then forced into the melted area and held in place until the metals re solidify.

The capacitor discharge cd stud welding method. 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. 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. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10.

This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing. Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration.

The welding process of cupped head pin welding corresponds with the contact type capacitor discharge drawn arc stud welding cd. The weld cycle can be completed in 0 01 seconds on material as thin as 0 020 0 5mm. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing. Capacitor discharge cd stud welding process.

Over the years welding. When triggered the energy discharges as a high current pulse melting the pip to produce an arc. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10. 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.

What are the two methods of stud welding.
