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.

Capacitor discharge stud welding process.

This high quality fusion arc weld is complete in milliseconds and is accomplished by one of two major methods. Capacitor discharge cd stud welding process. The welding process of cupped head pin welding corresponds with the contact type capacitor discharge drawn arc stud welding cd. 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.

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. The weld cycle can be completed in 0 01 seconds on material as thin as 0 020 0 5mm. What are the two methods of stud welding. Capacitor discharge stud welding eliminates drilling tapping punching riveting gluing and screwing.

Over the years welding. When triggered the energy discharges as a high current pulse melting the pip to produce an arc. Since the entire weld cycle is completed in milliseconds welds can be made without pronounced distortion burn through or reverse side discoloration. The welding stud is then forced into the melted area and held in place until the metals re solidify.

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

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. The capacitor discharge cd stud welding method. 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.
