英文摘要：

FFriction Stud Welding is a solid-state welding process without pressure environmental affect,which has been developing rapidly in the field of underwater connection for its excellent properties. Based on the characteristics of friction welding technology,the Friction Stud Welding process has been studied,and the influence of rotation speed on mechanical properties of Friction Stud Welding joints has been analyzed. Welding tests were carried out with different rotation speed respectively and tensile tests were done for welding joints. The results show that the high quality joints could be acquired under high rotation speed and high feed speed.
