Integrated double-seam double-arc TIG (Tungsten Inert Gas) welding system and Double-seam double-arc TIG welding method for T-shaped joints

Abstract

The invention relates to an integrated double-seam double-arc TIG (Tungsten Inert Gas) welding system and a double-seam double-arc TIG welding method for T-shaped joints. The structure of the Integrated double-seam double-arc TIG welding system for T-shaped joints is as follows: a welding tooling is mounted on a worktable, to-be-welded T-shaped joint parts are mounted on the welding tooling, the motion tracks of robots are programmed and set by electrical operation boxes, the robots are arranged upon robot guideways, the control hardware of each robot is completely optimized and integrated in a robot control cabinet, the robot guideways are symmetrically arranged on both sides of the worktable, a welding gun, an automatic welding stick feeder, a laser tracking system and a welding gun shield are assembled at the front end of each robot, each robot is provided with a pressure sensor and anticollision software, cooling water tanks are connected with welding sources, and in the working process of the robots, the argon arc welding sources are cooled by the cooling water tanks. The system not only decreases the labor intensity of workers, improves the working environment and increases working efficiency, but also remarkably improves the welding quality of joints.

Description

technical field [0001] The invention relates to a T-joint double-slit double-arc TIG welding integrated system and method, which are used in the field of welding automation. Background technique [0002] Robot welding is a breakthrough in the welding industry. Compared with the traditional welding method, it is a new flexible automation method. At present, the technical research on welding robots at home and abroad mainly focuses on five aspects: weld seam tracking technology, coordinated control technology of multiple welding robots and peripheral equipment, robot-specific arc welding power supply technology, welding robot system simulation technology and welding process methods for robots . But in general, there is still a certain gap between my country's welding robot technology and its engineering application level compared with foreign countries. [0003] The T-shaped structural parts on the aircraft are produced by double-slit double-arc TIG welding technology. Due t...

Problems solved by technology

[0003] The T-shaped structural parts on the aircraft are produced by double-slit double-arc TIG welding technology. Due to structural limitations, the parts are prone to defects such as undercut, burn-through, incomplete penetration, cracks, and welding bumps during the welding process. The amount of deformation is large, and it is difficult to ensure the forming quality of the parts
