Purpose: This paper presents the general aspects concerning the development of innovative ultrasonic welding technologies at ISIM Timisoara and the advantages of using ultrasonic metal joining, compared with conventional joining methods, in the automotive industry for joining multiwire connectors from copper and aluminium. Design/methodology/approach: In discussion is joining ultrasound multiwire copper conductors on copper 99.95% substrate, ultrasonic welding of copper and aluminium multiwire conductors onto Al99.95% support and welding dissimilar materials multiwire copper and aluminium conductors onto copper support. Findings: Comparison of experimental results through mechanical testing, electrical conductivity testing, digital microscopy imaging and ultrasonic compaction highlights the potential development and use of aluminium as a replacement of connection to the copper wiring in automotive equipment. Practical limitations/implications: The experimental results through mechanical testing, electrical conductivity, digital imaging microscopy, ultrasonic compacting, realized on Cu-Cu, Al-Al and Al-Cu samples, underscore the potential for using aluminium as a substitute for copper multiwire connectors in automotive industry. Originality/value: Statistics show that the automotive industry together with aerospace and military equipment industries represent by excellence the innovative technologies drive and consist as a sensitive indicator for society changes in the tech areas.
