Zusammenfassung:	The utility model relates to the technical field of tunnel primary support steel arch machining, in particular to a steel arch connecting plate welding clamp device. The fixture device comprises a handle, I-shaped steel and positioning bolts, the handle is welded to the upper portion between wing plates on the two sides of the I-shaped steel, positioning bayonets are formed in the lower bottom edges of the wing plates on the two sides of the I-shaped steel respectively, and two positioning buckles are arranged on each wing plate. Two positioning bolts perpendicular to the wing plate are arranged on the outer side of the wing plate on one side of the I-shaped steel. The fixture device provided by the utility model is formed by processing the same type of steel arch and the connecting plate, when the steel arch is processed again, only the two positioning bayonets of the fixture device need to be clamped on the wing plate of the steel arch, and then the connecting plate is butted with the positioning bolts of t
