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

Abstract

The invention discloses a tungsten electrode system of a welding machine head. The tungsten electrode system comprises a tungsten electrode rod, wherein a tungsten electrode is installed at the front end of the tungsten electrode rod, and tungsten electrode threads are arranged at the rear end of the tungsten electrode rod. The tungsten electrode rod penetrates through the middle of a housing of a gun body, the front end and the rear end of the tungsten electrode rod are exposed outside the housing of the gun body, and the tungsten electrode rod can drive the tungsten electrode to rotate. The welding machine head is infinitely rotatable and can rotate in different directions in the rotation process, the defecting angle of the tungsten electrode on the welding machine head is needed to be matched with the rotation direction when the welding machine head rotates so that the rotatable tungsten electrode can quickly adjust the its angle direction to adapt to the welding machine head in rotation direction, the welding quality of the welding machine head can be improved, and welded products 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 tungsten electrode system for a welding head. Background technique [0002] The high-temperature gas-cooled reactor evaporator project has not been processed and manufactured by any company 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 function 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 welding seam. A major 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 ordinary w...
