Complete Stud Welding

CD Weld Pins

CD Weld Pins are insulation pins for Capacitor Discharge stud welding designed for fastening blanket insulation to sheet metal and light-gauge steel surfaces. Installed using the CD stud welding process, the insulation pins create a permanent attachment point before insulation is impaled and secured with self-locking washers.

Complete Stud Welding supplies CD weld pins for insulation in low-carbon steel, stainless steel, and aluminum for HVAC systems, boilers, ovens, tanks, and industrial process equipment where clean, controlled welds are required.

  • Designed for CD Stud Welding
  • Permanent Insulation Attachment
  • Multiple Material Options
  • Compatible with Self-Locking Washers

Product Overview

CD Weld Pins provide a dependable solution for fastening insulation to sheet metal and light-gauge steel using the Capacitor Discharge stud welding process. The pins create a permanent welded attachment point while minimizing backside marking and maintaining the appearance of the finished surface.

Designed for thermal and acoustic insulation systems, these weld pins are compatible with self-locking washers and are available in multiple materials to suit HVAC, industrial, and commercial insulation applications.

CD Weld Pin Features

CD weld pins are engineered to provide a dependable attachment method for insulation systems installed on thin-gauge metal surfaces. Their compatibility with the Capacitor Discharge welding process allows fast installation with minimal backside marking while maintaining secure insulation retention.

Capacitor Discharge Welding Compatibility

Manufactured specifically for the CD stud welding process, these pins are suitable for welding to sheet metal and plate where low heat input and controlled weld quality are important.

Insulation Retention System

Once welded, insulation material is placed over the pin and secured using a compatible self-locking washer, creating a reliable mechanical fastening system for thermal insulation applications.

Multiple Material Choices

Available in copper-plated low-carbon steel, 18-8 stainless steel, and aluminum, allowing the weld pin to match corrosion resistance, conductivity, and project specifications.

Optional Protective Finishes

Galvanized weld pins and additional coating options are available for applications requiring enhanced environmental protection or extended service life.

Compatible Installation Accessories

CD weld pins are supported by matching self-locking washers and accessory components to simplify installation and maintain compatibility across insulation fastening systems.

Industrial Insulation Applications

Widely specified for HVAC ductwork, industrial ovens, boilers, tanks, refrigeration equipment, and hot or cold process systems requiring secure insulation attachment.
