Brief: Our team walks you through how Conical Tip Capacitor Discharge (CD) Weld Pins perform in common insulation attachment scenarios. You'll see a detailed demonstration of the welding process, from pin placement using a CD welder to the final step of securing insulation with a self-locking washer. This video provides practical insights into the application workflow, material options, and the equipment used for efficient and permanent attachment on various metal surfaces.
Related Product Features:

질문과대답:
  • What materials are available for these CD weld pins?
    These capacitor discharge weld pins are available in low carbon steel (typically copper plated), stainless steel (AISI grade 302/304/305 standard), and aluminum alloy (1100-H14 standard), with other grades and alloys available upon request to suit different application requirements.
  • How do I determine the correct pin length for my insulation application?
    The pin length should exceed the thickness of the insulation material to ensure there's sufficient length to securely attach the self-locking washer after the insulation is impaled on the pin. Standard lengths range from 3/4" to 7" to accommodate various insulation thicknesses.
  • What welding equipment is needed to install these pins?
    Standard capacitor discharge (CD) or arc stud welding equipment is required. A typical portable CD system consists of a controller/power unit, a CD gun with cables that serves as the pin holder, a ground cable with clamping connection, and special accessories to hold the pin in the gun during welding.
  • Can I get customized CD weld pins for my specific project needs?
    Yes, we support product customization including material selection, surface finish, wire diameter, and length according to your specific requirements. We also provide samples for quality confirmation before full production.
