Embodiment Construction
[0026] see Figure 1 to Figure 5 , shows a schematic diagram of the coaxial hybrid welding equipment for laser and plug brazing of the present invention. The coaxial composite welding equipment is mainly composed of a traction assembly 1 , an execution assembly 2 and a follower assembly 3 arranged sequentially from front to back. A front hinge 4, a telescoping mechanism 5 and a rear hinge 6 are connected sequentially from front to back between the traction assembly 1 and the follower assembly 3. in:
[0027] The traction assembly 1 includes a center bracket 31 extending forward and backward and a leading screw extending forward and backward rotatably installed thereon, and one end of the leading screw is connected with an adjusting motor 33 fixed on the central bracket 31 through transmission. The screw nut is screw-connected with the screw nut cooperating with the central support 31 against rotation, the screw nut is hinged with a short rod 34, and the other end of the shor...

The invention relates to a coaxial composite welding equipment and method for laser and plug brazing welding. Including the welding torch unit, the welding torch unit includes a fixed tube and a pressurized part and a loading part arranged in it. The pressurized part is fixed on the fixed tube and outputs linear power that expands and contracts along the length of the tube. The pressure plate on the top and the sheath that slides and sleeves along the axial direction of the fixed tube, the sheath and the pressure plate enclose a loading and unloading groove for unloading the solder column, and the sheath is connected to press the sheath when the sheath slides off the pressure plate. The return structure of returning to the original position; the nozzle of the fixed pipe or the position close to the nozzle is equipped with a laser generator that emits laser light to the inside and outside of the nozzle. The present invention utilizes the solder column of plug welding to form a shear connection between the connector and the pipeline, on the one hand, it utilizes the characteristics of good shear resistance of the solder column to improve the welding strength of the pipeline; on the other hand, laser heating is used to assist plug welding The method improves the working efficiency of the plug welding process, and is more convenient for industrial promotion.
Description
technical field [0001] The invention relates to a coaxial composite welding equipment and method for laser and plug brazing welding. Background technique [0002] At present, when welding the inner butt joints of long pipes, after butt jointing of two long pipes, surfacing welding is carried out after spot welding at the position of the butt joints, so as to complete the butt welding of pipes. However, in a long pipeline, this butt welding method will lead to a decrease in the performance of the pipeline against axial stress, which is not conducive to long-term use, increases leakage points, and shortens the maintenance life. Contents of the invention [0003] The purpose of this invention is to provide a kind of coaxial composite welding method of laser and plug brazing welding which improves the welding strength after pipeline butt jointing, and its technical scheme is as follows: [0004] Coaxial hybrid welding methods of laser and plug brazing, including: [0005] S1...
