Joining body, comprises first and second joining partners, which are partially connected to each other along connecting zone with weld seam

摘要

Joining body (10) comprises a first and a second joining partners (20), which are at least partially connected to each other along a connecting zone (40) with a weld seam (50), where the weld seam at least partially oscillates back and forth between the joining partners. Independent claims are also included for: (1) an electrochemical storage (100), preferably lithium-ion battery comprising at least one joining body; and (2) welding for producing of a joining body with the first and second joining partners, where connecting zone is formed with the weld seam.
