Exhaust pipe welding equipment

The utility model discloses exhaust pipe welding equipment which comprises a base, a machine frame and a vertical frame are fixedly installed at the top of the base, a three-jaw chuck is rotatably installed on the outer wall of the machine frame, a gear motor used for driving the three-jaw chuck is fixedly installed on the outer wall of the machine frame, a connecting rod is connected to the vertical frame through a first lifting mechanism, and the connecting rod is connected to the vertical frame through a second lifting mechanism. A welding gun is fixedly installed at the end, away from the vertical frame, of the connecting rod. When the device is used, after the three-jaw chuck is used for clamping an exhaust pipe, the two carrier rollers are used for supporting the other pipe section, the height of the carrier rollers is adjusted through the second lifting mechanism so that the two pipe sections can be aligned, and then the frame slides on the base so that the connecting sections of the two pipe sections
