Abstract
Segments of a clad pressure vessel are welded together along seams at which the cladding is removed to expose a steel backing, so that initially a groove opens out of the cladding toward the interior of the vessel at each seam. Batten strips cover the grooves, and each of those strips has a depressed center portion which fits into the groove for that strip to center the strip along its groove. The batten strip also has flanges which extend outwardly from the depressed portion to overlie the cladding, to which they are welded along their edges. Cover plates are welded over the ends of batten strips. Thus, the cladding, the batten strips and the cover plates totally isolate the steel backing of the pressure vessel from the interior of the vessel, so that the contents of the vessel will not corrode the backing.
