50mm 63mm 135mm 185mm 210mm Copper CD Weld Pins for Shipping Building

CD weld pins are precision-engineered insulation fasteners designed to attach insulation materials securely to metal surfaces. Primarily used in shipbuilding and heavy industrial applications, these pins are installed using capacitor discharge (CD) welding machines, ensuring a strong and permanent bond.

Once welded, insulation is impaled on the pin and held firmly with a self-locking washer. This method guarantees long-term stability, even in high-vibration or high-temperature marine environments.

Material Options & Advantages

Our CD weld pins are available in high-quality materials:

Copper-Plated Steel – Offers excellent corrosion resistance, especially suitable for marine applications

Zinc-Plated Steel – Cost-effective option for general industrial insulation

Stainless Steel 304 / 316 – High durability and corrosion resistance for demanding environments

Custom Materials – Available upon request to meet unique project requirements

Strict quality control ensures that every CD weld pin has consistent dimensions, weldability, and holding performance. Special sizes, nail points, and lengths can be customized to suit project-specific needs.

Specifications

Pin length should exceed insulation thickness for secure self-locking washer installation

Standard nail point, with blunt end available as a special order

Compatible with all standard CD welding machines

Additional Notes:

These CD weld pins are designed for optimal performance in marine and industrial environments. Proper CD welding provides maximum holding strength, reduces the risk of insulation detachment, and maintains long-term stability under vibration, high temperatures, or corrosive conditions. Custom lengths and base types are available for specific project applications.

Applications of CD Weld Pins

Marine insulation, including engine rooms and deck systems

Industrial wall, roof, and tank insulation

HVAC systems in marine and industrial facilities

Power plants, petrochemical, and chemical processing insulation

High-temperature or vibration-prone industrial equipment

Using CD weld pins ensures that insulation layers remain firmly attached, maintain system integrity, and minimize long-term maintenance. Their compatibility with CD welding machines makes them ideal for large-scale industrial and marine insulation projects.
