Abstract
A laminate sheet including a weldable margin is formed by laminating metal sheets having a core layer disposed therebetween. The core layer is formed of a core material which includes one or more of a viscoelastic, adhesive and acoustic material. The core layer is selectively distributed such that the laminate sheet includes an adhered region providing a laminate structure, and a non-adhered region including a weldable margin. The non-adhered region is adjacent an edge of the core layer and is characterized by a gap between the first and second metal sheets and by an absence of the core layer in the gap. The non-adhered region defines a weldable margin adjacent a core edge configured such that a weld is formable in the weldable margin without heat affecting the core layer. The laminate sheet can be joined by fasteners installed in the non-adhered region.
