[0013] This embodiment provides an arc starting and extinguishing plate structure, which includes a first panel 100 and a second panel 200. The first panel 100 and the second panel 200 are installed at the same arc starting point or the same arc extinguishing point of the weld of the base metal of the welded part, and the first panel 100 and the second panel 200 are arranged opposite to each other along the length direction D1 of the groove of the base metal of the welded part. The first panel 100 has a first welding surface 110 and a first back surface arranged opposite to each other along the thickness direction of the first panel, and a first top surface 120 and a first bottom surface arranged opposite to each other along the depth direction D2 of the groove of the base metal of the welded part. The second panel 200 has a second welding surface 210 and a second back surface arranged opposite to each other along the thickness direction of the second panel, and a second top surface 220 and a second bottom surface arranged opposite to each other along the depth direction D2 of the groove of the base metal of the welded part.

The first welding surface 110 is flush with the first groove surface 310, and the second welding surface 210 is flush with the second groove surface 320. Along the depth direction D2 of the groove of the base metal of the welded part, the lowest point of the top edge of the first welding surface 110 is not less than the groove depth from the bottom of the groove. Along the depth direction D2 of the groove of the base metal of the welded part, the lowest point of the top edge of the second welding surface 210 is not less than the groove depth from the bottom of the groove.

[0015] In some embodiments, the distance between the first welding surface 110 and the first back surface and the distance between the second welding surface 210 and the second back surface are not less than 12 mm.

[0019] Furthermore, the first top surface 120, the second top surface 220 and the surface of the base material 300 of the welded part where the groove is provided are flush, and the first bottom surface, the second bottom surface and the bottom of the groove are flush. When the depth of the groove of the base material of the welded part is equal to the thickness of the base material of the welded part, the distance between the first top surface 120 and the first bottom surface, and the distance between the second top surface 220 and the second bottom surface are the thickness of the base material of the welded part.
