ABSTRACT A welding head is mounted for movement relative to a fixed base about a plurality of axes. A laser beam, is transmitted from a laser generator to the welding head by an axially flexible but torsionally rigid transmission tube including one or more optically transmitting fibers. The transmission tube is rotatably mounted on the welding head for free rotation about the axis of the emitted laser beam. A lens is provided to focus the laser beam relative to the workpiece, and the welding head is moved relative to the laser beam generator and the fixed base. A mini-computer allows control of the moving means to direct the laser beam along the workpiece in a predetermined path. An apertured hood provides protection for the focusing lens, and an optional removable probe member provides assistance in programming the apparatus.
