Abstract
A connection part includes a metal body with a first electrical connection part connected to a first metal surface and a second electrical connection part connected to a second metal surface. At least one of the first electrical connection part and the second electrical connection part has a fixing face intended to be welded respectively to the first metal surface or to the second metal surface and an opposite face for applying welding power. The opposite face for applying welding power having a rough region. The rough region having a roughness Ra greater than 10 μm.
