Abstract
A metal wall, such as that of a vessel, is provided with cladding which is welded to the metal wall such that an elongated space is formed between the weld seams. The elongated space allows for the testing of the weld seams for leakproofness by closing off one end of the space and injecting a gaseous medium, or the like, into the space and gauging whether or not the medium exits via the weld seams. A plate made of rubber, plastic or the like may also be used in welding the cladding to the metal wall, which plate covers the unconnected ends of the two cladding parts making up the cladding layer for the metal wall.
