Key Features:

• Instantaneous Welding & No Heat Damage: Our pins adopt advanced capacitor discharge welding technology. The welding time is ≤ 3 msec, ensuring the ultra-low thermal radiation does not cause deformation or burn marks on thin metal sheets. This protects the integrity of equipment surfaces .

• Superior Weld Quality & Durability: Manufactured from high-grade materials, including low-carbon steel (copper-plated or galvanized) and Stainless Steel (304/316) . The hardened, precision-formed point ensures positive electrical contact for complete sheet-to-pin fusion .

• Versatile Material Compatibility: Designed to work with all major brands of CD stud welders and pin spotters . Available in standard gauges (10 GA, 12 GA) to accommodate various insulation thicknesses .

• High Construction Efficiency: One-step installation: weld the pin, impale the insulation, and secure with a self-locking washer. This process greatly shortens construction cycles and reduces labor costs .

• Corrosion & Temperature Resistance: Galvanized or copper-plated shanks exceed SMACNA corrosion standards . Pins function properly from 0°C to 121°C and are not adversely affected at temperatures up to 287°C . Stainless steel options provide excellent resistance to salt spray and harsh marine environments.

Application

• HVAC Systems: Securing thermal and acoustic linings to air ducts and ventilation components .

• Marine & Shipbuilding: Attaching insulation in engine rooms, accommodation areas, and on piping systems where vibration and corrosion resistance are vital .

• Industrial Equipment: Fixing insulation to boilers, pressure vessels, storage tanks, and turbines .

• Power Generation: Securing insulation in power plants and refineries .

• Metal Building Insulation: Attaching insulation to metal decking and structural steel.

Installation

1. Weld: Load the CD weld pin into the welding gun, position it on the clean metal surface, and trigger the weld. The flange creates an arc that fuses the pin to the metal in milliseconds .

2. Impale: Push the insulation material (e.g., mineral wool, fiberglass) firmly onto the protruding pins.

3. Secure: Place a self-locking washer over the pin tip and press down until it locks against the insulation surface .

4. Finish (Optional): For safety, snap a plastic dome cap over the exposed pin tip and washer .

FAQ

• What is the difference between CD weld pins and standard weld pins?
  CD weld pins use capacitor discharge welding, which has an ultra-low thermal radiation effect (≤ 3 msec weld time). This prevents deformation, burn marks, or residual traces on sheet metal surfaces, which is critical for thin gauges .

• What pin length should I choose for my project?
  The pin length should exceed the insulation thickness to allow for the self-locking washer to be placed and secured . For example, a 1/2″ pin is used for 1/2″ insulation.

• Can I weld these pins onto any metal surface?
  These pins are primarily designed for welding to mild steel, stainless steel, and aluminum sheet metal. For aluminum substrates, we recommend our Bi-Metallic Insulation Pins which feature an aluminum weld base .

• Can I place a custom order?
   Yes. Please contact our sales team with your specific requirements, and we will do our best to accommodate them.

• Do you provide samples? How can I get one?
  Yes, samples are available. Please reach out to our sales team with your sample request, and we will arrange shipment promptly.
