ABSTRACT:
A workpiece handling assembly for supporting and positioning each side of a multi sided workpiece in the path of a welding laser beam. The workpiece handling assembly includes a frame indexably movable in a plane perpendicular to the direction of the welding laser beam. The frame has a central opening therein through which the welding laser beam may be projected. A carrier secures the workpiece so that it is positioned within the frame in a plane in parallel overlying relationship with the aperture. The frame is rotatably supported about a transverse axis parallel to the aperture, the carrier is rotatably supported on the frame about a central axis which is orothogonal to the transverse axis. The workpiece supported in the workpiece handling assembly of the invention is movable through an angle of 360.degree. about the transverse axis and through an angle of 360.degree. about the central axis, so that all sides of the workpiece may be positioned in the path of the laser beam without removing the workpiece from the assembly.
