Abstract
A laser welded assembly and method of making. The laser welded assembly includes a first work piece having a thickness (T) defined between an external surface and a faying surface; a second work piece having a thickness (T) defined between an external surface and a faying surface of the second work piece; a weld seam having a core fusion zone extending from the external surface of the first work piece through the faying interface and at least partially into the thickness (T) of the second work piece; and a protruding fusion zone extending laterally from the core fusion zone adjacent to the external surface of the first work piece. The protruding fusion zone may be formed by post-heating or concurrently with the core fusion zone.
