product description
Multi-head Gantry Spot Welder, Gantry Spot Welder, Brand: Shanghai Haojing. Capable of welding common ferrous metals like steel and iron, as well as non-ferrous alloys such as stainless steel, copper, silver, and nickel. Also performs dissimilar metal welding, high-strength steel welding, hot-formed steel spot welding, and stud welding. Delivers high weld strength and aesthetically pleasing weld points. Shanghai Haojing’s multi-head gantry spot welding machines feature fully digital control via a human-machine interface touchscreen for intuitive operation. Performance can be expanded through PC programming. Custom fixture designs accommodate diverse workpiece welding requirements, and automated special-purpose machines can be engineered to enhance production efficiency.
Product Description:
The nut electrode comprises an electrode cover, electrode base, floating spring, air-blowing device, and positioning pin. Functions of each component are as follows:
Nut Electrode Cover: Directly contacts the workpiece plate or nut, serving as a conductor and heat sink. Requires excellent electrical conductivity and high softening temperature, typically made of chromium-zirconium copper.
Electrode Base: Supports the electrode, conducting electricity and dissipating heat. Features water cooling at the bottom and gas vents at the top for slag removal, usually crafted from chromium-zirconium copper.
Nut Positioning Pin: Ensures precise concentric alignment between the nut and the plate hole. It must withstand impact forces from placed components, shear forces from lateral nut movement, and high temperatures generated during welding while maintaining good insulation. Common positioning pins include ceramic pins, KCF pins, aluminum oxide pins, and SIM pins, with durability and price increasing in that order.
