ABSTRACT OF THE DISCLOSURE The invention provides an apparatus capable of effecting relative movement between the oval-like girth or circumference of a workpiece and tool means while maintaining the planar and radial workpiece surfaces in a fixed plane relative to the tool means as they are exposed thereto. The apparatus is especially useful in laser welding, and for this use, includes a base in a fixed plane relative to a focusing lens, means for effecting relative translational movement between the base and lens, and bearing and shaft means, including chuck means, for holding the workpiece in proper relation to the lens and for rotating the workpiece about longitudinal axes through the radii of the oval-like workpiece girth. The relative translational movement between the base and lens is utilized to cause the laser beam to transverse the planar surfaces of the workpiece whereas the rotational motion is utilized to cause the beam to traverse the radial surfaces of the workpiece while maintaining these latter surfaces in the plane established by the planar surfaces during their exposure to the tool means.
