Abstract
A laser beam projector to be employed in an automatic welding machine, such as a robot, includes an optical head that projects a laser beam and a holding and turning mechanism that holds and turns the optical head. The spot of the laser beam can be accurately located on the portion to be welded by turning the optical head by the holding and turning mechanism.
