A welding torch body of a welding machine head

Abstract

The invention discloses a gun body of a welding gun of a welding head. The gun body of the welding gun comprises a gun body casing, and the gun body casing is a hollow casing and is flat. A cooling system and a primary gas protection system are arranged in the gun body casing, the gun body casing is further provided with a tungsten electrode system, and the tungsten electrode system penetrates the gun body casing from the middle. A tungsten electrode in the tungsten electrode system is exposed out of the front end of the gun body casing, and the tungsten electrode on the tungsten electrode system is rotatable. The welding head is infinitely rotary, the gun body of the welding gun on the welding head can implement welding on a circumferential weld joint around the welding head in the rotating process of the welding head, and the welding quality can meet the quality requirements of nuclear power products.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding torch body of a welding head. Background technique [0002] The high-temperature gas-cooled reactor evaporator project has not been processed and manufactured by any enterprise in the world, so the high-temperature gas-cooled reactor evaporator project has been listed as a major national development project. According to the manufacturing technical requirements of nuclear power products, the existing equipment structure and functions cannot fully meet the processing and manufacturing requirements of the high-temperature gas-cooled reactor project, especially the all-position welding and 2G position welding of the high-temperature gas-cooled reactor evaporator assembly welds are industry-leading A big problem is that the groove of the weld is small and the weld bead is deep, and its quality requirements for welding are extremely strict. The weld obtained by wel...

Problems solved by technology

According to the manufacturing technical requirements of nuclear power products, the existing equipment structure and functions cannot fully meet the processing and manufacturing requirements of the high-temperature gas-cooled reactor project, especially the all-position welding and 2G position welding of the high-temperature gas-cooled reactor evaporator assembly welds are industry-leading A big problem is that the groove of the weld is small and the weld bead is deep, and its quality requirements for welding are extremely strict. The weld obtained by welding with ordinary welding equipment cannot meet the quality requirements of nuclear power products. Therefore, there is an urgent need for a New welding equipment that can solve the above problems
