Abstract

The invention relates to the technical field of welding, and discloses a preparation method of a temperature measuring seat for a superconducting feeder system, and the temperature measuring seat comprises a base and a circular tube which are welded with each other and are made of C10100 oxygen-free copper and 316L stainless steel. The preparation method comprises the steps that the round pipe is subjected to acid pickling, nickel plating is conducted after cleaning, an oxidation layer is removed from the base through an acid pickling method, the round pipe, the base and brazing filler metal are subjected to brazing assembly together through a welding device, the assembled welding device is integrally placed into a vacuum brazing furnace, and after the vacuum brazing step is executed, the furnace is opened, and the welding device is started. The welding device is simple in structure and convenient to use, contact between a base material and brazing filler metal can be guaranteed, the physical property that the difference between the base and the round pipe is large is effectively overcome, and reliable connection between the base and the round pipe is achieved.

Description

Technical field [0001] The present invention relates to the field of welding technology, specifically to a method for preparing a superconducting feeder system with a temperature measuring seat. Background [0002] As one of the key components of the nuclear fusion reactor, the superconducting feeder system is used to connect the room temperature power supply and the low-temperature superconducting magnet system to realize the transmission of excitation current in the superconducting magnet system. The use of superconducting feeder cooling system is extreme conditions, the current superconducting feeder system cooling pipe temperature is 4.2K and 77K respectively. In order to accurately collect temperature parameters on the cooling line, a large number of temperature measuring seats need to be arranged on the 4.2K and 77K cooling pipes. The general temperature measuring seat is welded by two materials, the physical properties of the two materials are quite different, in the vacu...
