Title:
WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/200888
Kind Code:
A1
Abstract:
A welding device (10) comprises a plurality of first welding electrodes (26, 28) which are rotatable, and a second welding electrode (42) which sandwiches a plurality of workpieces (32, 40) between the second welding electrode and one of the plurality of first welding electrodes. The welding device (10) further comprises a conductor (52) for conducting electrical current that is electrically connected to a welding power source (18). The plurality of first welding electrodes rotate simultaneously in a direction approaching or separating away from the second welding electrode. When doing so, the end faces of the first welding electrodes when approaching the second welding electrode come into contact with the conductor for conducting electrical current. Conversely, the end faces of the first welding electrodes when separating away from the second welding electrode separate away from the conductor for conducting electrical current.
