Diffusion Welder for Aluminum Busbar is designed for aluminum busbars, aluminum plates, copper-aluminum joints, and flexible conductive connectors. It uses controlled pressure and temperature to create solid-state bonding instead of melting the material. This process avoids oxidation, porosity, and brittle joint layers that are common in traditional welding. It is widely used in energy storage systems, power equipment, and new energy applications where electrical reliability and long-term performance are critical.
