<p>A monolithic tube blank (100) for forming a hydroformed product, the tube blank having at least one first section (102) having a first wall thickness and at least one second section (104) having a second wall thickness being greater than the first wall thickness. The wall thickness variation (106) along the axis (101) of the tube may be designed to be axially asymmetrical at any segment of the axis in order to facilitate differential stretching when bending or otherwise deforming the tube at that segment or at points proximate to the segment parallel to the axis of the tube. The tube blank is adapted to accept hydroforming stresses during a hydroforming process while precluding a reduction in wall thickness sufficient for stressing material of the tube blank to failure. Also contemplated is a method for forming a hydroformed product with such a tube blank.</p> |
