Embodiment 2

[0050] A superconducting strip joint welding method, using the above-mentioned superconducting strip joint welding device, comprising the following steps:

[0051] S1. Apply solder in advance to the parts to be welded on the front sides of the two superconducting strips 1 to be welded;

[0052] S2. Lap the parts to be welded with solder on the two superconducting strips 1 to form a lap joint, and then use the positioning block 3 to fasten the positioning on both sides of the two superconducting strips 1;

[0053] S3. Use the moving heating head 5 to move at a constant speed (preferably 0.3-3cm / s) from the first end of the lap to the second end to complete the first welding. During the movement of the moving heating head 5, move the thimble to press The head of head 6 contacts with the head of moving heating head 5 and moves together to prevent superconducting strip 1 from warping; during welding, the angle between moving heating pressing head 5 and superconducting strip 1 is c...

Abstract

The invention provides a superconducting strip joint welding device, which includes a flexible base plate, a positioning block, a moving driving mechanism, a moving heating head and a moving thimble pressing head; a positioning block and a moving driving mechanism are arranged on the flexible base plate, and the moving driving mechanism passes through The bracket is fixed with the movable heating head and the movable thimble indenter, and the movement of the bracket drives the movable heating head and the movable thimble indenter to move above the superconducting strip to be welded; the positioning block is arranged on the superconducting strip along the length direction of the superconducting strip. Both sides of the strip; the moving heating head and the moving thimble pressing head are also connected with a pressure control device. The resistance of the joint made by the device of the present invention is smaller than that welded by skilled welders, and more than half of the resistance of the joint welded by the overall pressing; the total thickness of the formed joint is 2um thinner than that of the joint formed by the overall pressing and welding; the joints are everywhere The thickness change is changed from ±3um to ±1um, which has better thickness uniformity and better mechanical properties.

Description

technical field [0001] The invention relates to the field of superconducting technology, in particular to a superconducting strip joint welding device and welding method. Background technique [0002] Since Professor Cameron Onnes first discovered superconductivity in his laboratory in 1911, superconducting materials and their applications have been one of the most active frontier research fields in contemporary science and technology. In 1986, the Federal German scientist J.G. Bednorz and the Swiss scientist K.A. Muller discovered the superconductivity of oxide ceramic materials, thereby increasing the critical temperature Tc of superconductors to 35K. In the following year, Chinese American scientist Zhu Jingwu and Chinese scientist Zhao Zhongxian successively discovered the yttrium barium copper oxide (YBCO) superconductor, with a critical temperature exceeding 90K. The critical temperature of this superconductor is higher than the temperature of liquid nitrogen (77K), s...
