Abstract

The embodiment of the invention discloses an automatic welding method and system for a nuclear-grade PE pipe. The method comprises the following steps that an electronic tag on a to-be-welded pipe isscanned; welding parameters corresponding to the electronic tag are read; and the welding parameters are imported into welding equipment, and the welding equipment carries out welding treatment on theto-be-welded pipe according to the welding parameters. According to the method, the electronic tag is arranged on the to-be-welded pipe in advance, so that the information of the to-be-welded pipe can be automatically identified, the influence of human factors is eliminated to the maximum extent by a simple means, and compared with manual welding, the welding quality is more stable; the application superiority of the automatic welding technology in the welding process of a main pipeline of a nuclear power station is more obvious, and the method has an important improvement effect on further improving the welding quality of the nuclear power station, further shortening the welding period, and further reducing the nuclear power construction cost.

Description

Technical field [0001] The invention relates to the field of nuclear power, in particular to an automatic welding method and system for nuclear-grade PE pipe fittings. Background technique [0002] During the welding of pipe fittings, the engineering volume is the largest in the construction and installation of nuclear power plants. The installation volume of pipe fittings for a single million-kilowatt nuclear power unit is nearly 125,000 m2. The welding quality of nuclear power pipe fittings is high, and the quality requirements are strict. The current manual welding method is not only inefficient, but the quality of the project is greatly affected by the welder's skills, and the quality cannot be guaranteed. [0003] For example, the output of the welding machine is determined by PE pipe fittings, and PE pipe fittings are often inconvenient to measure. At present, it is common to operate PE pipe fittings, and the difference of PE pipe fittings corresponds to the different weldin...
