Currently, the metallographic sample and the corrosion sample are taken on the daily witness sample by using wire cutting or water cutting.

Two U-shaped grooves are arranged at the two short sides of the base 1 respectively. The base 1 is fixed in the water cutting equipment through the four U-shaped grooves at the two short sides of the base 1. Two sample clamping plates 2 are installed at the middle positions of the two long sides of the base 1 respectively, and are used to tighten the metallographic sample and the corrosion sample needed to be cut on the welding sample through the second inner hexagonal cylindrical head screw 5. Two pressing plates 6 are installed at the middle positions of the two short sides of the base 1 respectively, and are used to fix the welding sample on the base 1 through the first inner hexagonal cylindrical head screw 4. The welding sample is a cuboid workpiece daily witness sample.

[0028] For example, the size of the first inner hexagonal cylindrical head screw 4 is M5 20. The size of the second inner hexagonal cylindrical head screw 5 is M4 10.
[0029] In the embodiment of the present application, the second inner hexagonal cylindrical head screw 5 on the sample clamping plate 2 is used to tighten the metallographic sample and the corrosion sample needed to be cut on the welding sample, which avoids the metallographic sample and the corrosion sample from flying out or being damaged during the cutting process, eliminates the risk of sample loss, and helps to enhance the cutting stability and improve the cutting quality. The sample clamping plate 2 is fixed on the base 1 through the inner hexagonal cylindrical head screw 4, and the water cutting equipment can cut the metallographic sample and the corrosion sample along the cutting path. After cutting, the metallographic sample and the corrosion sample can be taken out by removing the second inner hexagonal cylindrical head screw 5 on the sample clamping plate 2.

[0031] In at least one embodiment of the present application, the middle part of the base 1 is a boss structure, and the boss structure is used to support the welding sample. In this way, the base 1 can support the welding sample through the boss structure, which is easy to clamp and can also reduce the overall weight and ensure the cutting quality.
[0032] In at least one embodiment of the present application, the bottom height of the sample clamping plate 2 is consistent with the top height of the boss structure of the base 1. In this way, by setting the bottom height of the sample clamping plate 2 to be consistent with the top height of the boss structure of the base 1, the bottom of the welding sample is kept flush during cutting, which helps to improve the cutting stability.
[0033] In at least one embodiment of the present application, the sample clamping plate 2 is a single concave structure, and the inside is also a concave structure with a small groove structure for clamping the short boss of the welded sample. In this way, the water cutting can avoid bumping the short boss along the cutting path, and the metallographic sample and the corrosion sample can be easily cut and removed, avoiding the risk of loss of the metallographic sample and the corrosion sample and facilitating quick disassembly.

[0038] In at least one embodiment of the present application, the height of the positioning pin 3 is higher than the top height of the boss structure of the base 1. In this way, it is more conducive to quick positioning of the welded sample.
[0039] For example, the height of the positioning pin 3 can be slightly higher than the top height of the boss structure of the base 1. Figure 2 The plane is the plane positioned by the X-Y positioning system. The height refers to the shortest straight line distance in the Z direction perpendicular to the plane positioned by the X-Y positioning system. The structure of the positioning pin is described with reference to Figure 5 .
