Watch as we walk through the full process of copper diffusion welding for busbars using the HFTD-100-Q. From initial setup to real-world testing, this video demonstrates how the pneumatic-hydraulic system creates molecular-level bonds without solder or filler metals. See the machine in action as it joins multi-layer copper foils for EV battery packs, transformers, and switchgear—preserving flexibility and conductivity. Learn how the microcomputer controller and precision temperature control ensure consistent, repeatable results for B2B manufacturers.
