ABSTRACT:
An air cooling apparatus for a rotatable laser-type weld-line detecting device for an automatic welding machine having a welding torch applying welding to a welded portion of a workpiece to be welded, the air cooling apparatus being provided with a metallic heat-interruption housing enclosing the rotatable laser-type weld-line detecting device, a first air cooling system cooling the laser-type weld-line detecting device from around the outer surface of the device and the inner wall of the heat-interruption housing by the use of a low temperature cooling air under pressure, and a second air cooling system cooling the interior of a laser-type weld-line detecting unit emitting a detection purpose laser beam and a light receiving unit receiving and detecting the detection-purpose laser beam reflected from the welded portion of the workpiece.
