Embodiment 1

[0057] Such as Figure 2-7 The shown all-position pipe-pipe intersecting line automatic welding system includes: a welding power source 100, which provides a power source for the welding system.

[0058] The welding system is fixed on the outside of the pipeline in the circumferential direction, and to achieve welding in the circumferential direction, it needs to make a circular motion with the center of the pipeline as the center, so the transmission part 200 is required to provide a power source for it. Transmission part 200 comprises a motor-reducer 210, the gear 240 that is connected with reducer and chassis 220, and gear 240 is fixed on the chassis 220, and motor-reducer 210 is electrically connected with welding power source 100; Transmission part 200 also comprises a handle 230, the hand-held handle 230 is fixed on the casing of the motor. When in use, the hand-held handle 230 installs the system on the pipeline, which is convenient and quick to use.

Embodiment 2

[0066] This embodiment also provides a welding method for an all-position pipe-pipe intersecting line automatic welding system, including the following specific steps:

[0067] S101. Cleaning and requirements before welding: 1) When welding carbon steel pipes, the 8mm of the welding joint should be polished and derusted to expose the original metal color; 2) The cut of the pipe should be flat and vertical, and there should be no gap between the two pipes; 3) Use acetone or alcohol to clean the oil on the surface of the workpiece;

[0068] S102. Open the chuck and set it across the pipeline to be welded, and then the chuck clamps the pipeline under the action of air pressure;

[0069] S103, the intake pipe starts to intake air, the intake volume is controlled at 6L / min, the welding torch is preheated and the wire is fed, the diameter of the welding wire is 1.0mm, and the wire feeding speed is 1500mm / min;

[0070] S104. The motor-reducer works at a rotation speed of 0.15 rpm, d...

Embodiment 3

[0075] This embodiment also provides a welding method for an all-position pipe-pipe intersecting line automatic welding system, including the following specific steps:

[0076] S101. Cleaning and requirements before welding: 1) When welding carbon steel pipes, the 5mm of the welding joint should be polished and derusted to expose the original metal color; 2) The cut of the pipe should be flat and vertical, and there should be no gap between the two pipes; 3) Use acetone or alcohol to clean the oil on the surface of the workpiece;

[0077] S102. Open the chuck and set it across the pipeline to be welded, and then the chuck clamps the pipeline under the action of air pressure;

[0078] S103, the intake pipe starts to intake air, the intake volume is controlled at 8L / min, the welding torch is preheated and the wire is fed, the diameter of the welding wire is 1.0mm, and the wire feeding speed is 1800mm / min;

[0079] S104. The motor-reducer works at a rotation speed of 2.2rpm, dri...

Description

technical field [0001] The invention belongs to the field of welding technology, and more specifically relates to an all-position pipe-pipe intersecting line automatic welding system and a welding method. Background technique [0002] Intersecting line welds are very common and typical weld forms in actual industrial production, especially in the pipeline engineering and large pressure vessel production process, welding such spatial surface welds is labor-intensive and the welding quality is not easy to guarantee, so more and more More and more welding robots are used for welding of intersecting lines. The tube-tube intersecting line composed of two hollow circular tubes perpendicularly intersecting is a typical saddle-shaped space curve. The robot welding of the space curve includes welding processes such as flat welding, vertical welding, and overhead welding, and the welding method of all-position welding is required. , the force on the molten pool during welding is as f...
