The truss top chord connects to web members composed of double angles, with a work point located at the intersection. Diagonal bridging occurs as noted with a four-inch spacing from the connection point. Web members such as L4x4 angles utilize five-sixteenth-inch welds with a five-inch minimum length, while L3x3 angles use three-sixteenth-inch welds. Additional double angle members like L5x5 use five-sixteenth-inch welds on three sides, and L3 1/2x3 1/2 and L3x3 members use three-sixteenth-inch welds on three sides. A maximum clearance of one-half inch is maintained at the joint intersection.
