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： After a workpiece introduced into a welding station by a feed mechanism is positioned and fixed in the welding station, the workpiece is welded by laser beams guided by scan heads. Each laser beam is applied from one of the scan heads to a location on the workpiece through a beam path switching mirror of a beam path switcher to weld the location on the workpiece. Thereafter, the beam path switching mirror is retracted to guide the laser beam from another one of the scan heads to another location on the workpiece to weld the other location on 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： An outer surface of an object such as an automotive vehicle body is painted by conveying the object in one direction, moving a painting apparatus in a direction opposite to the one direction, and applying a paint coating to the outer surface of the object from the painting apparatus. The painting apparatus includes a plurality of paint spray guns which are displaceable in a direction transverse to the direction in which the object is conveyed. The paint spray guns are directed substantially perpendicularly to and spaced a predetermined distance from the surface of the object.

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.
摘要翻译：激光振荡器产生的热量部分地向框架辐射。辐射热部分地被冷却机构所吸收。剩余的热量通过将部分热量消散的室转移到阻止大部分热量的绝热面板。由激光振荡器产生的热量部分地向外辐射并由壳体朝向框架向内反射。反射的热量部分地被冷却机制所吸收。剩余的热量通过将部分热量消散的室转移到绝热板上，该隔热板阻止了大部分的热量。因此，由于激光振荡器产生的热量而引起的框架的任何温度上升都非常小，并且防止了由于来自激光振荡器的热而使框架变形。由于框架没有变形，所以从激光振荡器发射的激光束被施加到保持不变的期望位置。
