Welding process underwater repairs

Welding method of underwater repair welding a protection plate (3) to a estructurametalica (2) to cover a surface of the structure comprising a part to be repaired underwater, characterized porquela part to be repaired is sealed by the protection plate by welding the periphery of LaPlaca protection underwater, while inert gas (10) is supplied to a part of coaxially welding withthe laser beam (7) for a laser welding, in the chelates protection plate is provided with an aperture for releasing steam generated during welding from ater remaining between the protection plate and the structure, andthe aperture is closed after welding the outer periphery of the protection plate to the structure.
