Capacitor Discharge Stud Welding Process

When triggered the energy discharges as a high current pulse melting the pip to produce an arc.

Capacitor discharge 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. Capacitor discharge cd stud welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. 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. Capacitor discharge cd stud welding using very short weld times permits the welding of small diameter studs to thin lightweight materials.

Capacitor discharge stud welding is generally used to weld smaller diameter fasteners to thin base metals. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing. 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.

The welding stud is then forced into the melted area and held in place until the metals re solidify. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration. The capacitor discharge cd stud welding method. 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. And is especially beneficial when working with thin gauge materials due to the absence of reverse side marring or discoloration. 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.

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. 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.

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