摘要
采用熔化极惰性气体保护焊(MIG)、搅拌摩擦焊(FSW)两种常用的焊接制造方法,对现阶段新能源汽车使用频率较高的5052-H32、6082-T6、6005A-T6、6061-T6铝合金板材进行焊接,并对焊接接头进行高温力学性能测试及断口SEM检测。结果表明,无论MIG焊还是搅拌摩擦焊焊接接头,随着温度的升高,力学性能均呈现下降趋势,不可热处理强化型5xxx系铝合金与热处理强化型系铝合金MIG焊后断后伸长率变化相反。
In this paper,two common welding manufacturing methods,namely MIG and FES,are used to weld 5052-H32,6082-T6,6005A-T6 and 6061-T6 aluminum alloy plates,which are frequently used in new energy vehicles at this stage.The high temperature mechanical properties and fracture SEM of the welded joint are tested.The results show that the mechanical properties of both MIG and friction stir welded joints show a decreasing trend with the increase of temperature.The elongation of non-heat-treatment-enhanced 5xxx series aluminum alloy is opposite to that of heat-treatment-enhanced aluminum alloy after MIG welding.
