Abstract:
1. A method of forming a component from a tailored blank having two constituent parts, comprising the steps of providing a first constituent part having an aperture; providing a second constituent part of substantially uniform cross section having an embossment to fit the aperture and a surrounding flange to extend beyond the periphery of said aperture and overlap the first constituent part, the embossment being offset from the flange by the thickness of the first constituent part; positioning said first and second constituent parts to face to face relation with said second constituent part nesting said embossment within said aperture; securing the first and second constituent parts to one another to form a substantially planar tailored blank by laser welding said flange to said first constituent part by continuous welding between the flange and first constituent part, wherein said step of nesting said embossment in said aperture results in a flush surface between said first constituent part and said embossment; and deforming said blank to provide said component.
