Welding tool set for automobile radiator cross beam

The utility model relates to the technical field of automobile radiator beams, in particular to a welding tool set for an automobile radiator beam, which comprises a welding table, and guide rails are fixedly mounted at two ends of the top of one side of the welding table. The bracket is arranged, the second welding clamping air cylinder, the third welding clamping air cylinder and the jacking air cylinder are started, the third welding clamping air cylinder can fix the middle of a cross beam workpiece after being started, and the output end of the jacking air cylinder can drive the double-end pin rod to rise to abut against the bottom end of the sleeve after being started; after the second welding clamping air cylinder is started, the top end of the sleeve is pressed, then the thin air cylinder is started, the thin air cylinder pushes the bracket to one side of the cross beam workpiece, and due to the fact that the inner diameter of the sleeve grooves in the two ends of the cross beam workpiece is slightly l
