The variable frequency polymer diffusion welding machine is a welding method that contacts the surface of the workpiece at a certain temperature and pressure, causing fine liquid phases to form on the surface of the workpiece and gradually diffuse with each other to achieve bonding. It mainly welds the same multi-layer copper strip, aluminum strip, stainless steel strip, titanium zirconium tantalum strip, and can also weld multiple layers of dissimilar materials. Widely used for bus soft connection in industries such as new energy vehicles, power, petrochemical, and smelting.
