Abstract
A beam for use in construction equipment is made from tailor welded panels. At least one of the panels is made from at least two pieces of material such as steel welded together with the weld running the length of the beam. The weld between pieces of steel can either be parallel to the longitudinal axis of the beam, or the pieces can be tapered and the weld will be at an angle diverging from the longitudinal axis of the beam. The two pieces of material have a different compressive strength per unit of length in a direction transverse to the longitudinal axis of the beam. In some embodiments a top panel is welded to two side panels to form two top corners of the beam and a bottom panel is welded to the two side panels to form two bottom corners of the beam.
