specific Embodiment approach 1
[0027] Specific implementation mode one: combine Figure 1 to Figure 3 This embodiment is described. This embodiment is a thin-plate NiTi alloy electron beam welding rapid cooling and solidification fine-grain device, which includes a clamping body, a cooling copper 12 and a cooling copper fastening mechanism. The cooling copper 12 is arranged on the cooling copper fastening mechanism. Immediately above the snap grip body.
[0028] The welding object to be welded by the device 10 is a thin plate weldment, its length l can range from 85mm to 105mm, its width w can range from 125mm to 145mm, and its thickness h can range from 2mm to 5mm; the length, width and height of the device The ranges are L (300mm ~ 400mm), W (218mm ~ 225mm), H (80mm ~ 90mm).
specific Embodiment approach 2
[0029] Specific implementation mode two: combination figure 1 Describe this embodiment. This embodiment is a press-and-grab type clamp that specifically includes a clamp body 3, two support baffles 5 and four pressure grips 7. The middle parts of the upper end of the clamp body 3, the front, the rear, and both sides are respectively fixed with a support baffle. Plate 5, each supporting baffle plate 5 is provided with a pressure catch 7 on the outer side of both ends respectively, and the root of the pressure catch 7 is fixed on the upper end surface of the fixture main body 3 through fastening bolts 8 . The undisclosed technical features in this embodiment are the same as those in the first embodiment.
[0030] In this embodiment, when assembling the base metal 10 to be welded, the press-and-grab clamp body puts the base metal 10 close to the support baffle 5 on one side, and keeps a distance of 9 to 10 mm from the support baffle 5 on the other side. .

specific Embodiment approach 3
[0032] Specific implementation mode three: combination figure 1 This embodiment will be described. In this embodiment, the middle part of the upper end surface of the clamp main body 3 is provided with a protective groove 4 along the length direction. The undisclosed technical features in this embodiment are the same as those in the second embodiment.
[0033] The size of the protective groove 4 in this embodiment is 5mm×3mm×200mm. The protection groove 4 can prevent the electron beam from penetrating the sample and acting on the fixture, so as to protect the fixture main body 3 .
