Abstract
An apparatus and method for separating a pin tool from a shoulder tool, after the pin tool and shoulder tool have become welded together during a friction stir welding operation. In one exemplary embodiment a frame is used to support the shoulder tool. A fluid pressure actuating assembly is used for gradually exerting a force on the pin tool while the shoulder tool is held stationary within the frame. The gradually increasing force gradually breaks the weld and separates the pin tool from the shoulder tool without damaging the pin tool.
