    摘要: Scanning welding heads are introduced through respective openings of a workpiece into the workpiece by respective welding robots. When a laser beam is emitted from a laser beam emitting device, the laser beam is applied to a beam splitter of one of the welding robots, which reflects about 50% of the energy of the laser beam and introduces the laser beam into a scanning welding head. The beam splitter passes the remaining 50% of the energy of the laser beam therethrough. The laser beam that has passed through the beam splitter is reflected by a totally reflecting mirror of another scanning welding head. The scanning welding heads apply the laser beam to respective regions in the workpiece to weld the workpiece.

    摘要: A laser beam welding apparatus has a first laser oscillator for applying a laser beam to a right-hand automobile door, a second laser oscillator for applying a laser beam to a left-hand automobile door, and first through fourth laser beam path changing mechanisms for changing the laser beam path of the laser beam from the first laser oscillator in the event of a failure of the second laser oscillator, and changing the laser beam path of the laser beam from the second laser oscillator in the event of a failure of the first laser oscillator. Even when one of the laser beam oscillators fails to operate due to a malfunction, an overall welding line combined with the laser beam welding apparatus does not need to be shut down, and the laser beam welding apparatus can smoothly and efficiently weld the workpieces.

    摘要: The heat generated by a laser oscillator is partly radiated toward a frame. The radiated heat is partly absorbed by a cooling mechanism. The remaining heat is transferred through a chamber which dissipates part of the heat, to a heat insulating panel, which blocks most of the heat. The heat generated by the laser oscillator is partly radiated outwardly and reflected by a casing inwardly toward the frame. The reflected heat is partly absorbed by cooling mechanisms. The remaining heat is transferred through chambers which dissipate part of the heat, to the heat insulating panel, which blocks most of the heat. Therefore, any temperature rise of the frame due to the heat generated by the laser oscillator is very small, and the frame is prevented from being deformed due to the heat from the laser oscillator. Because the frame is not deformed, a laser beam emitted from the laser oscillator is applied to a desired position which remains unchanged.
