Problems solved by technology

[0004] However, although the speed of TIG welding has been increased, the traditional method of droplet transfer is still used, that is, the droplet is formed first and then transferred to the molten pool, and the controllability of the weld is poor.

Abstract

The invention belongs to the field of welding, and particularly relates to a uniform weld joint welding device. The uniform weld joint welding device comprises a base material, a tungsten electrode welding gun, a welding wire welding gun, a first power source and a wire feeding mechanism used for conveying welding wires, the first power source is connected between the tungsten electrode welding gun and the base material, and the uniform weld joint welding device further comprises a second power source, wherein a branch pipe is arranged on the tungsten electrode welding gun, the branch pipe isin communication with the welding wire welding gun, a branch tungsten wire is arranged on a main tungsten wire of the tungsten electrode welding gun, and the branch tungsten wire is located in the branch pipe; a coil is arranged in the side wall of the welding wire welding gun, one end of the coil is connected with the tungsten electrode welding gun through the second power source, and the other end of the coil is in sliding connection with the welding wire. Compared with a traditional welding device, according to the scheme, a traditional molten drop transition mode is avoided, the welding wire can be directly inserted into the molten pool, almost no distance exists between the welding wire and a molten pool, and after a coupling electric arc is formed, people can control variables through parameters such as welding current, voltage, welding speed and wire feeding speed, and the controllability of the weld joint is greatly improved.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a uniform seam welding device. Background technique [0002] Under the development requirements of welding automation and artificial intelligence, further increasing the welding speed is an important way to improve welding productivity. In general, the filler wire is fed under cold conditions. In order to improve the deposition speed and production efficiency of the weld, TIG welding can be performed with preheated wire. [0003] For example, the patent No. 201220075933.3 discloses a high-speed welding device with dual power sources and double electrodes, including argon tungsten arc welding torch (1), gas metal arc welding torch (2), argon tungsten arc welding machine welding power supply ( 3), MIGA welding power supply (5), MIGA welding machine ground wire (6), molten pool (7) and base metal (8), MIMA welding machine welding power supply (5) The positive pole of the argon t...
