  CD Stud Welding - The Process

Capacitor Discharge (CD) stud welding is a semi-automatic arc welding process. However, with CD welding small diameter fasteners (1/4" and under) are end welded to extremely thin gauge parent metal. The CD process operates on the principle of capacitor stored energy which is instantaneously discharged by the equipment system through a special weld "timing" tip.

Since the entire weld cycle is completed in several milliseconds, welds can be made to thin sheet without pronounced distortion, burn-through or discoloration. CD welding permits stud welding of dissimilar metals.

  CD Stud Welding - Applications

Providing fast welds on lightweight material with minimal distortion, CD stud welding is widely used in:
  • Restaurant Equipment - Stainless tables have CD studs applied to the underside to secure stiffeners, legs, drawer runner with no back side marking on the top side.
  • Signs - CD studs are applied to the back side of aluminum letters or internally in the signs to allow changeability.
  • Electrical and Metal Enclosures - Components are attached to the metal enclosure without marking the reverse side. The appearance is greatly improved and production rate is increased.
  • Electrical Contracting - CD studs are used to secure conduit and fixture to structural steel.
  • Conveyors - Stud Welding is used to attach fastener to half round runner bars. Weld Studs will not vibrate loose and leaves no area to collect debris.
  • Cookware - utensils, pots and pans, handles.
  • Insulation - Weld pins are used to attach insulation to metal surface. Self-locking washers are used in conjunction with the weld pins to fasten the insulation in place.
