Description

technical field [0001] The invention relates to the field of nuclear power welding, in particular to an automatic welding and feeding device and method for shear nails. Background technique [0002] The third-generation passive nuclear power plant single-unit structure module has more than 200 sub-modules, and the length of the shear nail is 152-311mm, and the diameter The total number of shear nails required for the structural modules of a single unit is about 400,000. At present, the shear nail welding of nuclear power structure modules is mainly based on arc stud welding, that is, using a hand-held arc stud welding torch for welding, which has the problems of excessive labor intensity and unstable welding quality. [0003] However, the existing automatic implanting and welding equipment on the market has a small volume of nail-feeding devices, and the inventors have found that there are mainly the following problems: [0004] 1) Due to the structural setting, it is onl...
