Connecting terminals of lithium-ion battery cells, comprises heating components using laser beam for forming molten bath in connecting region set in vibration generator, and solidifying molten bath to form strip-shaped weld by cooling

摘要

The method comprises heating two components (1, 2) using a laser beam (100) above their melting temperatures for forming a molten bath in a connecting region, mixing materials of two components in the connecting region, solidifying the molten bath to form a strip-shaped weld by cooling. The connecting region is positioned in a vibration generator (12) during part of the cooling. The vibration generator generates oscillations in different axes or vibrations in different directions. The vibrations are generated in a direction perpendicular to a joining plane between the components.

The connecting region is positioned in a vibration generator (12) during part of the cooling. The vibration generator generates oscillations in different axes or vibrations in different directions. The vibrations are generated in a direction perpendicular to a joining plane between the components. The oscillation has frequency of 100 Hz to 10 kHz. The vibration generator includes an ultrasonic or a piezoelectric vibrator. The laser beam is directed towards the components. An independent claim is included for a device for connecting two components consisting of different materials.
