Method and apparatus for laser-welding at least two conductor pieces, and assembly of at least two integrally bonded conductor pieces

Abstract

A method for laser-welding at least two conductor pieces includes providing an elongated first conductor piece having a first end portion and a first end face, and providing an elongated second conductor piece having a second end portion and a second end face. The first end face is arranged adjacent to the second end face. The method further includes producing a first laser spot on the first end face to produce a first weld pool, and producing a second laser spot on the second end face to produce a second weld pool. The first laser spot and the second laser spot are produced simultaneously. The first weld pool and the second weld pool subsequently merge to form a common weld pool.
