摘要： An underwater laser processing apparatus (100) includes an optical unit (3) and a nozzle (29). The optical unit irradiates a condensed laser beam generated by a YAG laser oscillator (35) to a certain point on a underwater workpiece (6). The nozzle has a gas exit for supplying a gas to the certain point. In the nozzle, an area surrounding the gas exit (25) extends to the surface of the workpiece. This area keeps the supplied gas between the nozzle and the workpiece to improve the underwater laser process.

摘要： A repair method for a structure having an open flaw (4) in a welding heat affected portion (3), including, removing at least a part of the open flaw and thereby forming a concave portion (8) in the welding heat affected portion, forming build-up weld layers (5) so as to fill the concave portion, treating a surface of the build-up layers to reduce tensile residual stress by means of at least one of laser peening, shot blasting and water jet machining. Also disclosed is an apparatus suitable for carrying out the repair method.
