Capacitor Discharge Stud Welding Process

The capacitor discharge cd stud welding method.

Capacitor discharge stud welding process.

This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration. When triggered the energy discharges as a high current pulse melting the pip to produce an arc. 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 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. The weld cycle can be completed in 0 01 seconds on material as thin as 0 020 0 5mm. And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration. The welding process of cupped head pin welding corresponds with the contact type capacitor discharge drawn arc stud welding cd.

Capacitor discharge stud welding usually cd stud welding for short and arc stud welding. What are the two methods of 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. 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.

This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10. Over the years welding. Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. 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. Capacitor discharge stud welding is generally used to weld smaller diameter fasteners to thin base metals. Capacitor discharge cd stud welding process. The welding stud is then forced into the melted area and held in place until the metals re solidify.

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