ABSTRACT:
A fixture for use in conjunction with welding workpieces by vibration welding including a pin adapted to assume two states, namely a first state in which the pin is movable to seek an aperture in the workpiece and is free to enter such aperture, and a second state in which the pin is rigidly fixed. The pin is attached to a plate which responsive to fluid pressure is either free to float in a generally lateral direction, or is clamped rigidly between two superposed plates.
