Abstract
A sheet metal piece includes a base material layer and one or more intermediate and coating material layers, along with a weld notch formed along an edge region of the piece. At least a portion of the coating and intermediate material layers is removed at the weld notch so that certain constituents from such layers do not affect the integrity of a nearby weld joint when it is subsequently formed along the edge region. Various methods of ablation, including laser ablation, can be used to form the weld notch.
