摘要

P the invention relates to the early detection of the formation of cracks in the construction elements. / p & & p & it relates to a process which comprises the formation of a cavity in the construction elements, for example in the vicinity of a weld, this cavity being connected by a pipe 9 to a vacuum source, for example. If a crack 15 is propagated in the construction element, the vacuum of the cavity is assigned and is detected and of the corrective measures can be therefore be considered. / p & & p & application to the control of the welds of the flat - forms of offshore drilling. / p
