Abstract
A linear friction welding system in one embodiment includes a welding control system operably connected to a hydraulic press and a ram, the welding control system including a processing circuit operably connected to a memory and configured to execute program instructions stored in the memory to bring a shaped charge portion of a first component to be welded into contact with a second component to be welded, and establish an initial scrub load pressure between the two components based upon a ratio between initial surface area of a contact initiation portion of the shaped charge portion and a final surface area of the first component. The processing circuit increases pressure between the components from the initial scrub load pressure to a target scrub load pressure before terminating oscillation of the ram and establishing or maintaining a weld load pressure.
