DETROIT – Ultrasonic welding, a high-tech manufacturing process used in the aerospace and medical industries, is helping ensure high quality for the new Cadillac ELR extended-range electric luxury coupe that goes on sale in North America in early 2014.
Ultrasonic welding’s key advantage is exceptional and predictable quality and performance from one battery pack to the next. Every ELR battery, for example, has close to 200 ultrasonic welds. Each is required to meet stringent quality requirements, enabling Cadillac to offer an eight-year/100,000-mile battery system warranty.
Short cycle times, low capital costs and manufacturing flexibility through the use of automation are other advantages of ultrasonic welding.
