Abstract
Welding apparatus featuring a right angle beam handling tube for directing a fixed laser beam from an entrance to the tube to a rotatably supported output reflector in a focus head mounted on an outlet of the tube. The tube has upstream and downstream duct sections which are independently extendible and retractable relative to their juncture, the juncture and a laser beam translating mirror mounted therein being movable only in a linear direction coincident with the incoming beam axis along the upstream duct section to ensure beam alignment with the entrance and outlet of the right angle beam handling tube while permitting the distances therebetween to vary to selectively position the focus head relative to a workpiece.
