Galvanized Steel Stud Welding Pins Insulation Dome Cap Self Locking Washer Manufacturer

Stud welding pins are high-performance fastening components designed to attach insulation materials firmly to metal surfaces in industrial and marine applications. Installed using CD or stud welding machines, these pins provide strong and permanent attachment, ensuring insulation remains stable even under vibration, extreme temperatures, or corrosive environments.

Once welded in place, insulation is mounted on the pin and secured with a self-locking washer, maintaining long-term durability and thermal efficiency. These pins are commonly used in shipbuilding, industrial HVAC systems, pipelines, power plants, and other heavy-duty insulation projects where reliable performance is essential.

Material Options & Advantages

Our stud welding pins are manufactured using premium materials:

• Copper-Plated Steel – Excellent corrosion resistance for marine applications

• Zinc-Plated Steel – Cost-effective solution for general industrial use

• Stainless Steel 304 / 316 – Superior durability and corrosion resistance for harsh conditions

• Custom Materials – Available upon request for specialized applications

Every pin undergoes strict quality control to ensure consistent dimensions, weldability, and holding strength. Custom lengths, diameters, and base types can be tailored to meet specific 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 and stud welding machines

Additional Notes:
These stud welding pins are engineered for maximum performance in marine and industrial environments. Proper welding ensures strong attachment, reduces insulation detachment, and maintains long-term stability under vibration, thermal cycling, or corrosive conditions. Custom base types and lengths are available for unique project requirements.

Applications

• Marine insulation, including engine rooms and ship decks

• Industrial wall, roof, and tank insulation

• HVAC systems for marine and industrial facilities

• Power plants, petrochemical, and chemical processing insulation

• High-temperature or vibration-prone industrial equipment

Using stud welding pins ensures insulation layers remain firmly attached, preserving structural integrity and reducing maintenance needs. Their compatibility with CD and stud welding machines makes them ideal for large-scale marine and industrial insulation projects.
