Abstract: A laser welding system is disclosed in which a high power laser produces the laser beam for delivery to a weld site. A transmitter is optically coupled to the laser and directs the laser beam to a spatially separated receiver. The receiver has an input alignable for receiving the directed laser beam and including optics for delivering the laser beam to the weld site. A pair of directable beam deflectors are employed for aligning the transmitter and the receiver. A pair of steering deflectors introduce the laser beam into the transmitter. A selectable mounting allows the laser to be secured at various orientations relative to the steering mirrors and the weld site. The transmitter and the receiver each have a detector positioned for receiving an alignment laser beam at a point which indicates alignment. The transmitter and the receiver include steppable drives for positioning their respective deflectors. The alignment laser is aligned at a starting block on the receiver detector and the transmitter detector.
