ABSTRACT:
A method of making steel beams in accordance with the present invention comprises sending web fabrication information to a web cutting station indicative of web sizes needed to make webs for steel beams and indicative of a web discharge sequence in which the webs are to be discharged from the cutting station. Steel plate is cut at the cutting station to form webs having the indicated web sizes. A series of the webs are transported from the cutting station to a beam station according to the web discharge sequence. Flange fabrication information is sent to a flange station indicative of flange sizes needed to make flanges for the beams and a flange discharge sequence in which the flanges are to be discharged from the flange station corresponding to the web discharge sequence. Steel stock is cut so as to form flanges having the indicated flange sizes. The flanges are transported to the beam station according to the flange discharge sequence so as to match the flanges with an associated one of the webs. The flanges and the webs are welded together to form beams at the beam station. Also included is a cutting station conveyor for alternating the elevation of slats and conveyor rollers during the web cutting process and a method of cutting webs using the conveyor.
