Embodiment 1
[0036] The embodiment of the present invention provides a method for unipolar magnetron electroslag surfacing welding with poles in a nuclear power plant, which is applied to a magnetron electroslag surfacing device for surfacing corrosion-resistant layers for large vessels in nuclear power plants. Please refer to figure 1, the strip-electroslag surfacing device includes: welding power supply 1, strip welding material 2, strip-feeding module 3, conductive tip 4, single magnetron module 5 and magnetron power supply 6; large container 7 is laid on the surface There are flux 8 and slag 9; such as figure 2 As shown, the strip electroslag surfacing method may further comprise the steps:
[0037] S1. Connect the positive electrode of the welding power source 1 with the contact tip 4, so that the strip welding material 2 connected to the contact tip 4 is charged, and the charged electrode is fed into the module 3 through the strip electrode The strip welding material 2 is sent to t...
Embodiment 2
[0048] Based on the same inventive concept, please refer to figure 1 , the embodiment of the present invention also provides a nuclear power plant unipolar magnetron strip electroslag surfacing device, including: fusion welding power supply 1, strip welding material 2, strip feeding module 3, conductive tip 4, magnetron module 5 and a magnetron power supply 6; the electroslag surfacing device with poles is used for overlaying the corrosion-resistant layer for the large container 7 of the nuclear power plant, and the surface of the large container 7 is covered with flux 8 and slag 9, wherein,
[0049] The strip feeding module 3 is connected to the strip welding material 2, and is used to send the strip welding material 2 to the surface of the large container 7 during the surfacing process;
[0050] The conductive tip 4 is arranged on the strip welding material 2, and is connected to the positive pole of the welding power source 1, and is used to charge the strip welding materia...
