Flexible laser welding head for sleeve-to-tube welding.

摘要

In one embodiment, a laser welding head is formed of a hollow tubular housing, and includes multiple focusing means for refocusing and realigning the laser beam if it is misaligned relative to the axis of the housing. In another embodiment, the housing is formed of a plurality of flexibly interconnected segments having at least one focusing means in each segment for realigning the beam and for directing the laser beam along interconnected linear paths.
