HFTD-600-Y Copper Diffusion Welding Machine
Product Overview
The HFTD-600-Y Copper Diffusion Welding Machine is engineered for diffusion welding of flexible copper busbars, copper strips, and other conductive components requiring stable, low-resistance joints. This advanced system combines a four-column hydraulic welding structure with medium-frequency power supply, controlled heating, and programmable welding parameters.
Supporting copper-to-copper, copper-to-nickel, and hard-copper-to-soft-copper bonding, the machine accommodates workpiece thicknesses from 0.5 to 25 mm. With a maximum hydraulic output pressure of 20 tons, 600 kVA medium-frequency welding transformer, and welding current up to 60 kA at 100% duty cycle, the HFTD-600-Y delivers exceptional performance for demanding flexible busbar and high-current copper connection production.
How the HFTD-600-Y Copper Diffusion Welding Process Works
The machine precisely controls temperature, hydraulic pressure, and welding time throughout the diffusion welding cycle. Unlike conventional filler-metal connections, this process brings mating metal surfaces together under controlled heat and pressure. For copper components, this method produces conductive joints while maintaining the precise geometry required for downstream assembly processes.
