【摘要】 瞬时液相扩散焊技术是一种新型的焊接技术,文章介绍了该焊接技术的原理,综述了国内外的研究现状及应用前景。国内对瞬时液相扩散焊技术的研究尚处于起步阶段,主要是针对一些异种难焊金属的焊接工艺;国外的研究更多的是对瞬时液相扩散焊工艺实现的一些关键因素的研究。关于瞬时液相扩散焊的质量检测技术主要有两种,射线探伤和超声波检测。瞬时液相扩散焊技术以其特有的优势已经广泛应用于航空、航天、核能以及其他技术领域,在管道焊接方面也具有很大的发展潜力。更多还原

【Abstract】 Transient liquid phase diffusion welding (TLP) is a new type welding technique. This paper describes the principle, the current research status at home and abroad and the application prospect of this technique. In our country TLP is just at the primary stage aiming mainly at the welding process for some dissimilar and difficult metals. The research work in foreign countries focuses on key factors related to implementing the process. There are mainly two quality inspection techniques of TLP, i.e. radiographic inspection and ultrasonic inspection. TLP has been widely applied in the technical fields of aviation, aerospace and nuclear energy as well as other fields because of its particular predominance. It has a significant developing potential in pipeline welding field.更多还原
