Plate components and weld configurations for fabricating a built-up structural steel wide-flange beam. The cross-section consists of a central web plate welded between top and bottom flange plates, with overall member dimensions defined by depth and width. Weld callouts indicate continuous fillet welds along the web-to-flange junctions, with options for continuous welding at the contractor's discretion. A specific note defines the weld sizing parameter where tw/2 equals half of the web plate thickness.
