Q235 Carbon Steel Annealing Weld Pins – Solution for Industrial and Marine Insulation

Weld pins are precision-engineered fasteners designed to attach insulation materials securely to metal surfaces in demanding industrial and marine applications. Using CD or stud welding machines, these pins provide a strong, permanent bond, ensuring insulation stability even under high temperature, vibration, or corrosive conditions.

Once welded in place, insulation is mounted and held securely with a self-locking washer, maintaining long-term durability and improving thermal efficiency. Weld pins are widely used in shipbuilding, HVAC systems, pipelines, power plants, and heavy industrial facilities.

Material Options & Advantages

Our weld pins are available in a variety of materials:

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

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

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

• Custom Materials – Available upon request to meet specialized project needs

All pins are manufactured under strict quality control to ensure consistent dimensions, strong weldability, and reliable holding power. Custom lengths, diameters, and base types are available.

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 weld pins are designed for optimal performance in marine and industrial environments. Proper installation ensures maximum holding strength, reduces the risk of insulation detachment, and maintains long-term stability under vibration, thermal cycling, or corrosive conditions. Custom lengths and base types are available for unique project requirements.

Applications of Weld Pins

• Shipbuilding insulation, including engine rooms and decks

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