摘要

采用焊前清理及无焊前清理两种工艺

深入研究焊前清理对铝合金厚板搅拌摩擦焊接头S线及性能影响

通过一系列试验对比发现

焊前清理有助于改善接头微观组织

同时焊前清理可以减弱S线

尤其是S线的分布宽度

有利于提高接头力学性能。

Abstract

The effect of pre-welding cleaning on the S-line and properties of the FSW joints of the aluminum alloy thick plates was studied by contrast of the specimens with pre-welding cleaning and without pre-welding cleaning. The following conclusions were drawn from a series of experiments. The pre-welding cleaning helped to improve joint microstructure. At the same time

the effect of pre-weld cleaning on the FSW joint was shown to weaken the S-line

especially the width of the S-line. The pre-weld cleaning could also improve the mechanical properties of joints.
