- Pointed tip: Designed for fast, accurate ignition and clean welds with minimal splatter or burn-through
What Is a CD Stud Used For?
CD studs are welded onto metal surfaces using a capacitor discharge welding process, which fuses the base of the stud to the parent material in a fraction of a second. This process is ideal for thin sheet metal (as low as 0.5mm) because it generates minimal heat, preventing distortion, discolouration, or burn-through on the reverse side of the panel.
Common applications include:
- Signage and shopfitting – fixing panels, letters, and displays
- Sheet metal fabrication – attaching brackets, fittings, and components
- Automotive bodywork and trim – fixing badges, trim, and panels
- Architectural cladding and facades – securing insulation, cladding, and fixtures
- Electrical enclosures and cabinets – mounting internal components
- General engineering and construction – wherever a strong, hidden, or low-profile fixing is required
Why Choose CD Welding Studs?
- No visible marking on the reverse side of the workpiece
- Fast, efficient installation compared to drilling and tapping
- Strong, permanent weld joint with high pull-out strength
- Minimal heat distortion, ideal for polished or painted surfaces
- Consistent, repeatable results for high-volume production
