Abstract
The invention relates to a method for manufacturing a hollow, elongated structural element, where a first and a second blank () are led through an oven () for heating to working temperature and are led through rollers () with profiled surfaces for pre-forming in one or more steps. The blanks are each led through a forging press with a number of cooperating dies, the blank being worked in a number of steps () into halves of an essentially finished product, having a cross-section substantially in the shape of a U-profile with a predetermined varying height, width and thickness of material along its length. The second blank () is essentially a copy of the first blank (). In a final step () the blanks are joined together into a composite hollow structural element (). The invention also relates to a structural element manufactured according to the method.
