摘要
Friction welding （FW） is a process of solid state joining which is used extensively in recent years due to its advantages such as low heat input,production efficiency,ease of manufacture and environment friendliness.Friction welding can be used to join different types of ferrous metals and non-ferrous metals that cannot be welded by traditional fusion welding processes.The process parameters such as friction pressure,forging force,friction time and forging time play the major roles in determining the strength of the joints.In this investigation an attempt was made to develop an empirical relationship to predict the tensile strength of friction welded AA 6082 aluminium alloy and AISI 304 austenitic stainless steels joints,incorporating above said parameters.Response surface methodology （RSM） was applied to optimizing the friction welding process parameters to attain the maximum tensile strength of the joint.
搅拌摩擦焊是一种固态连接工艺,具有低的热量输入、高的生产效率、容易操作和环境友好等优点而被广泛使用。搅拌摩擦焊能够焊接不同类型的黑色金属和有色金属,而传统的熔焊则不能。焊接工艺参数如摩擦压力、顶锻压力、摩擦时间和施压时间对接头的强度起主要作用。本研究旨在建立一个经验方程去预测搅拌摩擦焊AA6082和AISI304不锈钢接头的拉伸强度。采用响应面法去优化搅拌摩擦焊工艺参数,从而得到接头的最大拉伸强度。
