High Stable Precision Copper Flexible Conductor Diffusion Welder Hydraulic Work
This pneumatic-hydraulic diffusion welding machine is an advanced joining system based on the principles of molecular welding and polymer diffusion, specifically designed for high-reliability welding of copper flexible conductors, composite busbars, and dissimilar metals. Utilizing pneumatic-hydraulic boosting technology, it generates precisely controlled high pressure. Combined with high-current resistance heating, it creates the high-temperature, high-pressure environment necessary for atomic diffusion at the workpiece interface, achieving a solid-state metallurgical bond without melting. This process perfectly integrates the fast response of pneumatic systems with the stable high pressure of hydraulic systems, offering significant advantages of low energy consumption, long service life, and low noise. It is particularly suited for manufacturing critical components such as power battery interconnects for new energy vehicles, large-section flexible busbars for the power industry, and conductive straps and expansion joints. It is a core piece of equipment for ensuring the reliability of electrical connections under demanding conditions of high current, high vibration, and long service life
