Capacitor Discharge (CD) welding studs, also known as CD-type welded bolts, are precision-engineered fasteners designed for quick and permanent attachment to metal surfaces using a low-heat, high-speed welding process. These studs are widely used in sheet metal fabrication, electrical enclosures, stainless steel products, and more.
When made from stainless steel, CD welding studs offer excellent corrosion resistance, strength, and long-term durability—even in demanding industrial or outdoor environments.

⚙️ Applications
CD welding studs are ideal for thin sheet metal (as thin as 0.5 mm), providing strong welds without burn-through or backside marking. Common application industries include:
- HVAC Systems – Fastening brackets, insulation pins, or electrical terminals
- Electrical Cabinets & Panels – Securing components without drilling holes
- Automotive & Rail Industry – Lightweight, vibration-resistant internal fastenings
- Kitchen Equipment – Stainless steel surfaces with visible or hidden studs
- Metal Furniture – Clean aesthetic fastenings for visible panels
- Elevator & Escalator Manufacturing – Internal structure components
