Abstract
The linear friction welding apparatus of this invention includes two vibrating assemblies, which simultaneously vibrate both work pieces along different weld axis within the plane of the weld interface during the weld process. The LFW apparatus allows one or both work pieces to be independently vibrated against one another along different weld axis to control and concentrate the application of thermal energy across the weld surfaces caused by friction in certain areas of the weld surface and certain times during the weld process.
