摘　　要：以接头形式2.5 mm+4.0 mm的5083铝合金为对象,研究采用回填式搅拌摩擦点焊(RFSSW)时下扎深度、旋转速度、焊接时间三个主要工艺参数对接头剪切拉力、交叉拉力及其断裂方式的影响规律。结果表明,当下扎深度2.8 mm、旋转速度2 000 r/min、焊接时间7.5 s时,剪切拉力达到最大值14.62 k N,交叉拉力达到最大值5.49 k N。In this paper,the study object is aluminum alloy 5083 with the joint form of 2.5 mm＋4.0 mm. Researched the influence of main process parameters such as pressing depth, rotational speed and welding time, on the shear tensile ,cross tension and fracture mode by refill FSSW. The results show that the maximum shear tensile is 14.62 kN and the maximum cross tension is 5.49 kN when the pressing depth is 2.8 mm, the rotational speed is 2 000 r/min and the welding time is 7.5 s.
