| 摘要 |
The present invention is a method of friction welding of metal members characterized by initiating friction welding in a state in which insert material formed from a metal having a melting point (temperature in Celsius) of 60 - 80% of the melting point (temperature in Celsius) of a metal member is inserted between joining surfaces, which are facing surfaces of a pair of the metal members, and melting and extruding the insert material. Thus, while negative effects due to high temperature heating as was done conventionally are eliminated, joining quality equivalent to or greater than the conventional is obtained in a short period of time. |
