Underwater laser processing device including chamber with partitioning wall
First Claim
1. An underwater laser processing system comprising:
- a laser torch including a condenser lens;
a laser torch driving mechanism for changing an emission position of said laser torch; and
a laser torch containing chamber for containing said laser torch and said laser torch driving mechanism;
wherein said chamber for containing said laser torch has, at a portion for emitting laser light, a water-tight partitioning plate movable for allowing said laser torch to come in or go out of said chamber for containing said laser torch;
a processing chamber provided at a portion for emitting laser light and processing a structure to be processed in such a manner as to be in contact with said structure to be processed in order not to allow water to flow in said processing chamber; and
said processing chamber is provided integrally with, or independently from, said chamber for containing said laser torch, and is provided with an inert gas injection mechanism, an inert gas exhausting mechanism, and a water discharging mechanism.

Abstract
An underwater laser processing system has a laser torch; a laser torch driving mechanism for changing a laser emission position of the laser torch; and a chamber with one end opened to an external environment, which contains the laser torch; wherein a partitioning wall for preventing permeation of water is provided between a free end of the chamber and the laser torch. The system is used for detecting a sensitized portion and repairing it at one time using a sensitization detecting arrangement. Moreover, it is used for forming an alloying layer by melting a sprayed coating film, and for forming a new surface layer by emitting a laser beam through a solution containing a metal component.
