The strength of a brazed joint does not vary appreciably with the different brazing materials , but depends to a large extent upon the maintenance of proper clearance between the outside of the tube and the valve socket 如果采用不同的钎焊材料，其钎焊连接的强度并不见得很好，强度大小取决于管道外壳与阀门套管之间正常的、大范围的清洁维护工作。
This article introduced the development and ti - based brazing material used for titanium alloys , and analyzed the relationship between metallurgical structure and mechanical property of welding joint , mechanical behavior under high temperature 、 corrosion resisting property and fatigue capability of the joint were also represented 本文介绍了钛合金用的钛基钎焊料的发展现状，重点评价了钛基钎料钎焊后组织与力学性能的关系，以及钛基钎料的高温力学性能、耐蚀性以及疲劳性能等。
