Abstract:
1. A laser working apparatus comprising: a laser head provided with a reflector; a laser oscillator configured to output a laser beam for welding and a visible beam, the laser oscillator being connected to the laser head such that one of the laser beam and the visible beam is inputted to the laser head; a mover configured to move the laser head, the mover being attached to the laser head; and a controller configured to control the mover so as to move the laser head in accordance with a previously taught movement route, and configured to also control the laser oscillator and laser head such that the laser oscillator outputs the laser beam and the laser beam inputted to the laser head irradiates a work piece in a predetermined working pattern, wherein the controller comprises a working position checking controller configured to control the mover so as to move the laser head in accordance with the previously taught movement route, and configured to also control the laser oscillator and laser head such that the laser oscillator outputs the visible beam and the visible beam inputted to the laser head irradiates the work piece in a checking pattern indicating a reference position for the predetermined working pattern, wherein the working position checking controller is provided with two alternative modes, the two alternative modes including a central position mode in which the visible beam irradiates the work piece at a central position of the predetermined working pattern and a working pattern mode in which the visible beam irradiates the work piece in a same pattern as the predetermined working pattern.
