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 superconductive strip joint welding device. The device comprises a flexible bottom plate, positioning blocks, a moving driving mechanism, a moving heating pressure head and amoving center pressure head, wherein the positioning blocks and the moving driving mechanism are arranged on the flexible bottom plate, the moving driving mechanism is fixed to the moving heating pressure head and the moving center pressure head through a support, and the support moves to drive the moving heating pressure head and the moving center pressure head to move above a superconductive strip to be welded; the positioning blocks are arranged on the two sides of the superconductive strip in the length direction of the superconductive strip; and the moving heating pressure head and the moving center pressure head are further connected with a pressure control device. According to a joint produced through the device, the resistance is less than that of a joint welded by a skilled welding person, and is less than that of a joint which is pressed and welded as a whole by a half or more; the total thickness of the formed joint is 2 [mu]m thinner than the joint which is pressed and welded as a whole; and the thickness change of the joint is changed from + / -3 [mu]m to + / -1 [mu]m, the thickness uniformity is better, and the dynamic performance is better.

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...
