Capacitor Discharge

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.


  • Low Cost Studs
  • Low Cost Equipment
  • Fastest Process
  • Easy to Jig
  • No Gas required
  • Clean Welds, NO finishing
  • Ideal for Production Systems...
     
    e.g CNC, auto stud feed

The CD Weld

When triggered, the energy discharges as a high current pulse, melting the pip to produce an arc. Spring pressure forges the stud onto the molten surface to ensure complete fusion across the flange.

  • High Current Pulse
  • Pip Melts
  • Spring Presses Stud to Job
  • Welds across flange
The weld duration is less than 4 milliseconds.

This process is ideal for use on thin gauge cold rolled sheet where reverse marking can be minimised or eradicated. Penetration into the parent material is minimal.

CD Studwelding controllers are lightweight & hand portable. They are lower cost than either the Drawn Arc or Short Cycle equipment and they run from single phase 230/110Volt 50 Hz supply

Requirements

To use CD Studwelding, the parent material must be clean and flat. The sheet may be Mild Steel, Stainless Steel, Aluminium Alloy, Pure Aluminium or Lead Free Brass.

  • Stud sizes:
  • Sheet Thickness :
  • M2.5 – M10
  • 0.7mm min
