The current production process of the exhaust pipe mainly includes: forging, forming, welding, heat treatment and surface treatment steps, and the exhaust pipe welding fixture is the fixture for welding the auxiliary exhaust pipe.

[0003] Since the exhaust pipe needs to be welded as a whole at the outer circle of the welding position during welding, and most of the exhaust pipe welding fixtures in the prior art do not have the function of flipping the welding position, and cannot adjust the welding position of the exhaust pipe according to the actual welding situation, when it is necessary to weld the other side of the exhaust pipe, the exhaust pipe needs to be disassembled and reassembled, which not only makes the welding process of the exhaust pipe more cumbersome and complicated, but also multiple disassembly and assembly will have an adverse effect on the welding strength of the exhaust pipe welding position, resulting in poor application effect of the exhaust pipe welding fixture.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an exhaust pipe welding fixture.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0032] like Figure 1 to Figure 2 As shown, a plurality of sets of storage bottom rods 201 are slidably equipped with telescopic supporting rods 202. The telescopic supporting rods 202 support and fix the arc-shaped supporting member 203, and the arc-shaped supporting member 203 is height-adjusted by controlling the telescopic supporting rods 202 to extend and retract.

[0033] like Figure 1 to Figure 2 As shown, a locking bolt 204 is threadedly connected to one side of the storage bottom rod 201, and one end of the locking bolt 204 located in the storage bottom rod 201 contacts the telescopic support rod 202.
