摘　　要：摩擦螺柱焊是摩擦焊技术的的一种,在焊接过程中,焊机带动螺柱旋转并轴向进给,当旋转螺柱与基板接触时开始摩擦剪切过程,并对基板上的接触部位加热,摩擦过程持续一小段时间后螺柱停转,然后维持或增大压力进行顶锻完成焊接。国外试验研究表明该技术在水下环境亦能获得较好的连接质量,因而在水下牺牲阳极等非重要钢结构物的连接方面具有巨大的应用潜力。国内应该优先结合海洋石油工业的实际发展需求,尽快开展相应的应用基础研究工作。Friction stud welding is one of the friction welding technologies.In the welding process,the stud is driven to rotate and vertically fed by the welding machine.When the rotated stud contacts with the substrate,the rubbing and shearing process begins and the contacted area on the substrate is heated.After the rubbing and shearing process a short time,the rotated stud stops and the axial force maintains or increases for upsetting to complete the welding process.The foreign experimental research illustrated that the friction stud welding can achieve good bonding properties under the condition of underwater environment,so it occupies great potentials in the underwater connectivity of sacrificial anodes and other non-important steel structures.The domestic researchers should combine with the practical developmental requirement of national oil industry in priority,to initiate the related basic research work for application as soon as possible.
