[0046] Working principle: When the gas pipe needs to be welded, the pipe 14 is picked up and placed between the C-shaped movable plates 23, and then the electric telescopic rod 20 connected to the rotating shaft 19 is started, and then the rotating shaft 21 and the C-shaped movable plate 23 are pushed together, so that the T-shaped frame 24 can be stably moved relative to the inner side of the T-shaped groove 18, and finally the protective pad 22 contacts the outer wall of the pipe 14, so as to stabilize the pipe 14, and then the circular heating frame 13 is inserted into the welding position of the two pipes 14, and then the electric melting machine 9 is started, and the electric fuse 15 is used to transfer heat energy to the circular heating frame 13, so as to perform welding operation on the pipe 14, thereby avoiding the two pipes 14 from welding during the welding process. The welding position is misaligned, which affects the welding efficiency and improves the practicality of the welding device. Later, during the welding process, the gas pipe will produce some pungent gases. At this time, the servo motor 206 fixedly connected to the hollow column 205 is started, and the fan blade 208 is driven. Then, the wind force generated by the fan blade 208 is blown to the inside of the hollow box 1, which helps to enter the inside of the exhaust pipe 204, and enter the purifier 202 to purify the odor. Finally, the treated odor is discharged through the exhaust pipe 203. Therefore, it is achieved that the odor generated by welding can be effectively treated and then discharged into the air, thereby avoiding air pollution and not affecting the physical and mental health of the operator.
