[0044] Specifically, in the technical solution adopted by the welding tooling proposed in Example 1 of the utility model, a guide groove 201a extending in the same direction as the limit member 201 is provided on the second part of the limit member 201, and the guide groove 201a penetrates the second part in a direction perpendicular to the second part. The width dimension of the guide groove 201a in the second direction Y is smaller than the nut part of the locking screw 203, and the locking screw 203 penetrates the guide groove 201a and the screw part thereof is screwed to the mounting plate 110 where the clamping assembly is located. After the metal frame is placed in the placement groove 111 of the welding tool, the L-shaped limit piece 201 hinged to the hinge seat 202 can be flipped over so that the second part of the limit piece 201 can be flipped to the top side of the metal frame under the guiding action of the guide groove 201a on the locking screw 203. Then, the limit piece 201 is pressed against the top of the metal frame by screwing the locking screw 203, thereby achieving compression and limiting of the metal frame, preventing relative sliding between the metal frame and the metal round rod 3 during the welding process, effectively improving the relative positioning accuracy of the metal frame and the metal round rod 3, and thus improving the yield rate of the finished product after welding.
