PROBLEM TO BE SOLVED: To provide a laser beam maintenance and repair device capable of using high energy intensity laser beam, facilitating machining with a laser beam and extending an applicable range. SOLUTION: This device is provided with a laser beam oscillator 7, a beam transmission means 3 connected to transmit a laser beam from the laser beam oscillator 7 and an irradiation head 13 to condense a laser beam from the beam transmission means 8 and to irradiate a work. In this case, the beam transmission means 8 has tubular beam transmission members 9a-9h constructed liquid tight, a reflecting member is arranged inside the beam transmission members 9a-9h, at least one among mechanism imparting horizontal turning, horizontal extension/retraction, vertical turning and vertical extension/retraction is arranged. |
