搅拌摩擦焊工艺参数对锁底接头性能的影响
Effects of friction stir welding parameters on mechanical properties of lock joint
摘要
Abstract
An extensive investigation is carried out on the friction stir welded joints of 7055-T6 aluminum alloy lock with thickness of 4 mm.The effect of the FSW pin length and AS location on the mechanical property and hook defect of lock joints is analyzed.The results show that there is a hook defect on the cover plate side,the migration amount of the hook defect is the main reason for the change of the mechanical properties.The optimal parameters:the pin length is 4 mm,the tensile strength of lock joint in AS location on the base plate is 424.0 MPa,and the strength coefficient of joint is 0.70.关键词
