摘　　要：当前搅拌摩擦焊工艺往往需要较大的焊接力和扭矩,导致焊接设备体积和质量都比较庞大,不利于搅拌摩擦焊技术在现场组装制造、就位修复等方面的应用。为了开发小型化搅拌摩擦焊设备,拓展搅拌摩擦焊技术的应用范围,就必须要研究低载荷搅拌摩擦焊工艺,以降低搅拌摩擦焊过程中所需的各向载荷。基于这一实际应用背景,从焊具设计和焊接工艺调控等角度对当前国内外的低载荷搅拌摩擦焊工艺的研究现状进行了阐述,并对这一方向的研究趋势进行了展望。The traditional friction stir welding(FSW) equipments are commonly characterized by large size and weight due to the high force and torque requirement for FSW process.The large-scale FSW equipments greatly limit the application of FSW technology for both assembly and 'in-situ' repairing welding.In order to develop the small-scale FSW equipments and widen the application scope of FSW technology,it is necessary to investigate the low-load FSW process to reduce all kinds of loads required for welding.Based on this practical application background,the domestic and international research status on low-load FSW process were illustrated from the aspects of tool design and process control,and the prospect of the investigation on this topic was expected.
