Capacitor Discharge Stud Welding Process

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

Capacitor discharge stud welding process.

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. 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 is generally used to weld smaller diameter fasteners to thin base metals. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10.

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 cd stud welding process. 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. 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. This process is suitable for studs ranging in size from 4 40 m3 thru 3 8 16 m10. 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. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration.

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. This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. 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 using very short weld times permits the welding of small diameter studs to thin lightweight materials. Over the years welding. The capacitor discharge cd stud welding method. Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure.

Capacitor discharge stud welding usually cd stud welding for short and arc stud welding.
