Abstract
A linear friction welding head apparatus for dual axis forging, the apparatus including three sets of orthogonal actuators for providing X-, Y-, and Z-planes of apparatus movement for providing Y-axis oscillation, a first forge load along a first forge axis, and a second forge load along a second forge axis. A method for dual axis forging for welding including providing a welding head for applying first and second forge loads along X- and Z-forge axes to weld at more than one interface. The forge loads may be applied at right angles to each other and have magnitudes corresponding to weld interface length.
