And S3, sensing the welding seam of the steel cylinder through an ultrasonic sensor, wherein the ultrasonic sensor can sense the steel cylinder for a long time in a conventional state, when the welding seam of the steel cylinder rotates to a sensing line of the ultrasonic sensor, the welding seam is in a venting state, the information feedback of the ultrasonic sensor is different from the conventional state, the information of the state is transmitted to a controller, and the controller can control a motor III 331 to stop running, so that the welding seam of the steel cylinder is in a designated position.
And S4, controlling the U-shaped frame 343 to drive the two laser welding gun heads 344 to perform linear motion along the steel cylinder welding seam through the second electric push rod 342, performing internal and external synchronous welding on the steel cylinder welding seam through the two laser welding gun heads 344, upwards moving the welded steel cylinder through the movable mounting frame 37 to loosen after the welding is completed, controlling the jacking roller 3241 to jack up at the front lower position of the steel cylinder through the first electric push rod 3242, rotating and separating the steel cylinder from the outside of the locking mechanism 3 by taking the compression roller 31 at the rear position of the lower side of the steel cylinder as a fulcrum under the stress of the steel cylinder, and continuously performing the steps to weld the next steel cylinder.
