Research on Diffusion Welding Technology of Al-Li Alloys without Interlayer
-
摘要: 概述了铝锂合金超塑成形/扩散焊接技术的现状, 研究了铝锂合金无中间层扩散焊接工艺, 通过选取适当的工艺参数和焊接前化学处理, 使焊件获得较高的剪切强度。Abstract: In this paper, the development of SPF/DB welding technology of Al-Li alloys is summarized. Without interlayer, the better shear strength of the welding test-piece of Al-Li alloys is obtained by choosing appropriate technological parameters and chemical disposing before the diffusion welding.
