ABSTRACT:
Exoscopes for joining tubular like objects has a housing made in two sections which clamp around the objects to be welded together. The end of the objects are held in place by an internal stent which claps the ends of the object together. Optic fibers or the like connected to a laser source terminate in the housing in such a way that the conducted laser beam is directed simultaneously circumferentially around the abutting ends to be welded. There are no moving parts during the welding.
