| Abstract: | Bellows is the core element of the self-regulating J-T cooler with bellows.The welding quality directly determines the performance and the reliability of the self-regulating structure.In this paper,the effects of the high temperature welding process with different heat input and different cooling methods on the performance of electrodeposition bellows commonly used in the J-T coolers are studied from the aspects of stiffness,hardness,and microstructure and so on. |
