Vitesco Technologies uses state-of-the-art green lasers from TRUMPF for energy-saving welding of copper. With the introduction of the new green laser equipment for copper welded joints, Vitesco Technologies is among the pioneers in the serial use of this new solution. Compared with infrared laser systems – the standard in copper welding to date – the use of green lasers can reduce energy consumption by up to 20 percent, depending on the application, and thus the CO2 footprint per laser welded joint. At the same time, production becomes more sustainable by the fact that green laser systems cause virtually, no copper spatter during welding, which otherwise means more effort during production.
The green laser system works in the visible light spectrum with a wavelength of 515nm. Compared to the infrared laser welding technology with a wavelength of around 1030 nm used to date, the welding process with the green laser is more energy- efficient and controlled.
The green laser technology is being used at Vitesco Technologies for the first time for the production of sophisticated battery management electronics for the BMW Group.
The energy consumption for the welding process could be reduced by 4% just by substituting the beam source from the infrared laser system to the green laser equipment.
