An electrochemical machining tool includes a tool main body which includes an electrode having a tubular shape extending along an axis and formed of a conductive material having flexibility, the electrode through which an electrolyte flows toward a distal end side, and an insulating layer coated on an outer circumferential surface of the electrode so as to expose a distal end surface of the electrode. In the electrochemical machining tool, a hole part serving as a fluid discharge part configured to discharge the electrolyte flowing through inside of the electrode toward the outside in the radial direction of the tool main body is formed at a portion of a position in the circumferential direction of the tool main body.

A powder metal cladding nozzle which is coaxially attached to a laser processing head that irradiates a process portion (W) with a laser beam (L) and that discharges powder metal (P) to a laser beam irradiation portion in the process portion (W). The powder metal cladding nozzle includes a body portion (2) that has a ring-shaped powder metal holding space (7) in which the powder metal (P) is held; and a nozzle portion (3) that is connected to the body portion (2) and that has plural discharge passages (18) which are communicated with the powder metal holding space (7) and which open at an outlet (19) for discharging the powder metal (P). The powder metal holding space (7) is formed in the body portion (2) and is divided into plural powder metal holding regions corresponding to plural supply passages (10) that open into the powder metal holding space (7) and that supply the powder metal (P) to the powder metal holding space (7).

A method of laying a pipeline is described in which both internal and external weld passes are performed in order to weld together the pipe sections. The method includes arranging a pipe section adjacent to the end of a pipeline thereby defining a circumferential joint to be welded, performing an external weld pass, with for example GMAW—MIG torches, on the root of the joint to be welded during which weld material is deposited in the root of the joint to be welded, thereby forming a root weld, and then performing an internal weld pass, with for example a GTAW—TIG torch, on the root weld during which the root weld is melted and re-shaped. The method has particular application in relation to pipes clad with corrosion resistant alloy.

Gas turbine blades which simplify the formation of cooling channels provided inside the turbine blades while simultaneously avoiding loss of turbine blade strength and rigidity due to forming of the cooling channels. Cooling channels provided in the interior of a gas turbine blade include a plurality of straight channel-like base-side elongated holes extending in a longitudinal direction at a base side of the turbine blade, a plurality of straight channel-like tip-side elongated holes extending in a longitudinal direction at a tip side of the turbine blade, and a plurality of communicating hollow portions interposed at connection portions between the two types of elongated holes to allow the two types of elongated holes to communicate with each other, and have larger cross-sectional areas than the channel cross-sectional areas of both elongated holes. The communicating hollow portions are formed to match the position of a platform portion of the turbine blade.

PROBLEM TO BE SOLVED: To automatically repair the fissuring arising in a member to be repaired, such as a turbine blade. SOLUTION: The entire part of the blade is photographed in a wide visual field by a remote camera 1 to obtain a wide-visual-field image and this wide- visual-field image is subjected to image processing, by which the position of the fissuring on the blade is obtained as fissuring rough position information. The fissuring is photographed by an optical cutting method in a narrow visual field at every previously regulated spacing along the fissuring in accordance with the fissuring rough position information and this narrow-visual-field image is subjected to image processing, by which the position, width and depth of the fissuring are determined at every previously regulated spacing and are used as fissuring point sequence data. The fissuring is thereafter repaired according to the fissuring point sequence data. COPYRIGHT: (C)2003,JPO
