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 wire feeding system for a welding head. The wire feeding system comprises a wire feeding rod, a wire feeding rod support and an adjusting screw, wherein one end of the wire feeding rod support and the wire feeding rod are fixedly connected to be a whole at a predetermined angle, the other end of the wire feeding rod is fixedly connected with the adjusting screw, and thus the wire feeding rod is driven by the rotatable adjusting screw to rotate. The rotating angle of the wire feeding rod is small, so that it is convenient to control a welding wire to move in a small range, and accordingly the relative position between the welding wire and a molten pool is adjusted. The welding head is infinitely rotary, the wire feeding system on the welding head can adjust the relative position relations of the molten pool and the welding wire according to concrete working conditions of a circumferential weld joint around the welding head in the rotating process of the welding head, and thus 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 wire feeding system of a welding machine 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 obtain...
