CD Weld Pins – Reliable Fasteners for Marine and Industrial Insulation

Capacitor Discharge weld pins are precision insulation fasteners engineered for secure attachment of insulation materials onto metal surfaces in marine and industrial applications. Designed for use with capacitor discharge (CD) welding machines, these pins allow rapid installation while providing strong, long-lasting support for insulation systems.

After the pin is welded in place, insulation is easily mounted and secured using a self-locking washer, ensuring stable and durable fastening even under vibration, high temperature, or harsh marine conditions.

Material Options & Advantages

Our CD weld pins are available in a range of high-quality materials to meet demanding project requirements:

• Copper-Plated Steel – Provides corrosion resistance and reliable performance in marine environments

• Zinc-Plated Steel – Cost-effective and suitable for general industrial insulation

• Stainless Steel 304 / 316 – Excellent corrosion resistance and durability, ideal for shipbuilding

• Custom Materials – Available upon request to meet unique project specifications

All pins are manufactured with strict quality control to ensure accurate dimensions, consistent weldability, and strong holding power. Special sizes, pin diameters, and nail points can be customized according to project requirements.

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 Capacitor Discharge weld pins are engineered for optimal performance in marine and industrial environments. Proper welding with a CD machine ensures maximum holding strength, reduces risk of insulation detachment, and maintains long-term stability under vibration, high temperature, or corrosive conditions. Custom lengths and base types can be provided for specific project requirements.

Applications of CD Weld Pins

Capacitor Discharge weld pins are widely used in:

• Shipbuilding insulation, including engine rooms and deck systems

• Industrial thermal insulation projects

• HVAC systems and pipelines in marine facilities

• High-temperature or vibration-prone industrial equipment

By using CD weld pins, installers ensure that insulation layers remain firmly attached, maintain system integrity, and reduce long-term maintenance costs. The combination of robust materials and CD welding installation makes these pins ideal for demanding shipbuilding and industrial applications.
