Example illustrations are directed to methods and apparatuses comprising battery cells having weld joints. In an example method, a laser is moved to a shoulder of a battery cell. The method may further include micro welding with the laser a first line segment on the shoulder of the battery cell and moving the laser a distance on the shoulder of the battery cell. The method may also comprise micro welding with the laser a second line segment on the shoulder of the battery cell in response to moving the laser the distance. Example battery cell assemblies, e.g., for a battery pack, may have a battery cell and a weld joint on a shoulder of the battery cell. The weld joint may include a first micro weld line segment and a second micro weld line segment separated by a distance.

The present invention relates generally to laser welding in the manufacture of sheet metal components, such as for example automobile components. More particularly, the present invention relates to a process and a system for forming a localized anti-corrosion surface layer along a laser welded joint (weld bead), subsequent to the laser welding together of sheet metal plates having an anti-corrosion surface layer pre-coat.
