Ultrasonic welding, a process typically used in the and medical industries, helps high quality for the new Cadillac ELR electric luxury coupe on sale in North America in 2014, according to a Cadillac release.

Cadillac is using ultrasonic technology often used in airplanes to make the ELR battery s quality more uniform.

to the press release from the ELR s battery pack features 200 ultrasonic welds, each to meet stringent quality that enable Cadillac to an eight-year, 100,000-mile warranty on the ELR s system. The release said advantages of ultrasonic welding short cycle times, low costs, and manufacturing flexibility by use of

General Motors Center for Research President and CEO Jay Baron Ultrasonic welding is a far superior technology in applications where it can be Cadillac’s innovative process produce batteries with quality compared with methods – and do it more efficiently. This is one of technology development that is pervasive in today’s world vehicles.

The ELR battery packs are at General Motors Brownstown Assembly plant near where automated ultrasonic is used to join metal tabs on the ELR s 16.5 kWh battery The welding process used for the ELR was used for the Chevrolet Volt, the said, giving these on how the process works:

Ultrasonic welding uses tools called an anvil and to apply rapid mechanical to the battery’s copper and aluminum This creates heat friction, resulting in a weld does not require melting-point or joining material such as soldering or fasteners.

An integrated vision system is used to a reference image of the weld prior to the operation to achieve accuracy. Quality operators electrode tabs before and welding, and the system monitors of signal processing features each weld.

GM vice president of Global Engineering Catherine Clegg This effort is an outstanding of teamwork between research and engineering. It has helped integrate the use of technical, complex technology a sustainable manufacturing process, means we can consistently deliver batteries to our customers for the Cadillac

We first told you about the ELR some time ago. a luxury sport coupe tweaked Chevrolet Volt guts, the ELR battery pack is and located longitudinally along the car s between the front and rear The pack itself weighs 435 lbs and is 5.5 in length and supplies enough to allow the ELR to put down 295 ft-lbs of on-demand.

GM estimates the ELR will about 35 miles on electricity before a gasoline engine in GM a range extender kicks in to energy to the ELR s electric drive
