Hydraulic Clamping Boom Tack Welding FixtureTack welding fixture designed to handle 2 different booms with no tooling changeover. Subassemblies are positioned and clamped on the fixture then a welder tacks components in place. After fixture was assembled at our facility a complete laser inspection is done to certify critical positions. Due to the extreme size and weight of the boom parts, hydraulic cylinders were used to push and clamp boom and loose pieces together. The fixture was designed to hold the locating items within +/-.006".
