Abstract

The invention discloses a full position pipe-pipe intersecting line automatic welding system and a welding method and belongs to the technical field of welding. The full position pipe-pipe intersecting line automatic welding system comprises a welding power source, a transmission component, a rotating component, a clamping component and a wire feeding component. The transmission component comprises a motor-speed reducer, a gear and a chassis, wherein the gear and the chassis are connected with the speed reducer, the gear is fixed to the chassis, and the motor-speed reducer is electrically connected with the welding power source. The rotating component comprises a rotating disk, transverse swing sliding frames, a welding torch and a tooth ring matched with the gear, the welding torch and the tooth ring are fixed to the rotating disk, the transverse swing sliding frames are transversely fixed to the rotating disk, the rotating disk is fixed to the chassis, and the motor-speed reducer drives the rotating disk to enable the welding torch to rotate. The clamping component comprises a base and two chucks. The two chucks are symmetrically arranged and rotationally connected with the base.The base is fixedly connected with the chassis. The wire feeding component comprises a welding wire connected with the welding torch. The full position pipe-pipe intersecting line automatic welding system is simple in structure and convenient to use, through control over the welding parameter and the welding position, correction of the circular degree error and groove preparation error of a welded piece is achieved, the depth consistency of a weld joint is guaranteed, the quality of the weld joint is high, and normal use of pipes is guaranteed.

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...
