Complete Guide to Ultrasonic Metal Welding: Joining Copper, Aluminum & Nickel Dissimilar Metals
In the fields of new energy vehicles, photovoltaic energy storage, semiconductor packaging, and precision electronics manufacturing, metal joining processes are facing multiple challenges in electrical conductivity, thermal stability, and long-term reliability. Traditional welding methods such as resistance welding and brazing often affect joint life during dissimilar metal joining due to excessive growth of brittle intermetallic compounds. Ultrasonic welding technology, with advantages such as solid-state metallurgical bonding, no solder or flux required, and low heat input, is becoming a mainstream solution for joining high-conductivity metals. Based on Winna Technology's 15 years of industry experience, this article systematically reviews the range of metal materials that ultrasonic welding machines can weld, the advantages of dissimilar metal welding, and key points for model selection,...
