Abstract
An apparatus and method for forming a stringer are provided. The stringer generally includes a web having a desired corrugated configuration and first and second flanges welded to opposite edges of the web. The apparatus includes a support structure, a strongback that is supported by the support structure, and a plurality of dies that are adjustable relative to the strongback. The strongback defines a corrugated contour surface corresponding to the desired corrugated configuration of the web. The dies define corresponding forming surfaces and are configured to be advanced toward the strongback to thereby form the web to the desired corrugated configuration between the contour surface of the strongback and the forming surfaces of the dies. Further, the apparatus can receive the flanges of the stringer in a predetermined configuration with the web so that the flanges can be welded to the web while the web is supported by the strongback and dies in the desired corrugated configuration.
