Double-sided simultaneous joining of medium carbon steel by center drive linear friction welding

Abstract

In general, two materials are welded by conventional linear friction wedding (LFW). On the other hand, we developed a center drive double-sided linear friction welding method in which an insert material was sandwiched between two materials to be joined and the insert material was vibrated while the three materials were pressed. In this study, three medium carbon steel S45C plates were welded simultaneously by this novel LFW method. After the welding experiment, the mechanical properties and joining interface structure of the obtained joints were investigated.
