文摘The physics phenomena of copper and stainless steel in the process of forming friction welding joint are recorded and observed by the interrupted test method.The test shows that the butt friction welding process of copper and stainless steel bar can be divided into three stages approximately: the adhesion at the beginning friction stage, the friction inside the copper and the plastic ring expansion, and the friction on the bound surface of copper-stainless steel and in stainless steel. During the process,the friction surface was transformed twice.
