Capacitor Discharge (CD) Weld Nuts
CD weld nuts are an important product series of Guangzhou Yonglong Hardware Manufacturing Co., Ltd. CD weld nuts use the capacitor discharge welding process to weld nuts onto thin sheet surfaces, providing reliable threaded connection points. This process features extremely short welding time (1-3 milliseconds), minimal heat-affected zone, and low sheet distortion, making it ideal for thin sheet (0.5mm-2mm) welding applications.
CD weld nuts are widely used in automotive manufacturing, electrical appliances, sheet metal fabrication, and enclosure manufacturing. In applications where components need to be threaded onto thin sheets, CD weld nuts provide an efficient and reliable solution. After welding, the nut and sheet form a metallurgical bond with high connection strength that resists loosening from vibration.
We offer CD weld nuts in various specifications with materials including copper-plated low carbon steel and stainless steel. Thread sizes range from M3 to M12. All products comply with national and industry standards. For inquiries: 020-81762527, 020-81012789
