E80 electrodes provide the specified weld sizes, including half-inch fillet welds at the web and flange connections. Gusset plates interface with the structural members, showing symmetrical three-foot-four-inch dimensions and detailed edge spacings. Equal spacing of three inches and five inches on center governs the bolt layout across the joint plates.
