摘要
搅动摩擦焊是在摩擦焊基础上派生出来的。它不受焊件必须是旋转对称体的限制，适于焊铝合金等熔点较低材料，焊缝为固态组织，避免了普通熔焊可能产生的各种缺陷，是解决Ａｌ－Ｌｉ合金、金属基复合材料焊接问题的好方法。
Friction stir welding releases the process from restriction to rotationally symmetrical bodies A tool positioned above the center line of the joint is rotated fast enough to produce thermal plasticity and moved along the joint Friction stir welding, unlike fusion welding, involves no melting and resolidification and therefore does not create the cast microstructure, comparatively lange HAZ potential distortion,and residual stress typical of fusion welds The artical overviews the advantages and current status of friction stir welding
