CLOSED-LOOP LASER-WELD ASSEMBLIES

Abstract: systems, methods, and assemblies for forming or employing closed-loop laser-welds are described. closed-loop laser-welds may be formed by, for example, actuating a laser on a substrate at a first point to initiate a weld and scanning the laser along a starting weld path, along a main weld path, and along an ending weld path. the starting weld path is from the first point to a second point. the main weld path is from the second point to a third point. the ending weld path is from the third point to a fourth point. the laser is scanned from the second point to the third point such that a bead of the main weld path defines an inner perimeter and an outer perimeter. the outer perimeter defines a closed-loop laser weld. the first point and the fourth points are within the inner perimeter.
