Laminate including weldable regions

A method of forming a weldable structural component having an adhered region and a weld portion, the method comprising:

• forming a laminate sheet by:
• selectively applying a core material to a first metal sheet such that the core material is distributed on only a portion of the first metal sheet to define the adhered region of the laminate sheet;
• wherein the remainder of the first metal sheet is characterized by an absence of core material to define a non-adhered region of the laminate sheet;
• laminating the first metal sheet to a second metal sheet such that the core material is disposed between and bonded to the first and second metal sheets to form the laminate sheet including a core layer made from the core material;
• wherein the core layer includes a core edge defining a boundary between the adhered region and the non-adhered region;
• wherein after laminating to form the laminate sheet:
• the adhered region is defined by the first and second metal sheets and the core layer bonded therebetween;
• and
• the non-adhered region is defined by a gap between the first and second metal sheets and the absence of the core material in the gap;
• wherein the non-adhered region extends continuously along and adjacent to the core edge to define a weldable margin;
• wherein the weldable margin includes:
• the weld portion immediately adjacent the core edge;
• and
• a trim portion immediately adjacent the weld portion;
• wherein the weld portion is intermediate the trim portion and the core edge;
• the method further comprising:
• applying a holding force to the trim portion of the laminate sheet;
• and
• applying a forming force to the adhered region of the laminate sheet while continuing to apply the holding force to the trim portion of the laminate sheet;
• wherein applying the forming force:
• forms the laminate sheet into a structural component including the adhered region and the weld portion;
• and
• removes the trim portion from the laminate sheet.
