PURPOSE:To provide a tube inside repairing device by which the discover, the repair and the inspection of cracks or holes generating on a tube wall inside a piping can be effectively executed with a short time. CONSTITUTION:The device is provided with an illuminating means 11 which is connected to a light source device and illuminates a tube inside, an objective lens optical system 13 picking-up an observing image of the tube inside on a solid image pickup element 12, an observed image transmitting means 14 for transmitting the observed image to CCU, a laser beam transmitting means 15 composed of a fibre, etc., to transmit a laser beam for welding generated from a laser beam oscillator, an annular condenser lens 16 that the laser beam is converged on the wall surface of tube inside, and a repairing member attaching part 17 composed of C ring 17a, etc., for attaching the repairing members by arranging them in a top end part 4 of a tube inside repairing device 1. The tube inside repairing device 1 discovers a defective place 2a of a tube part 2, welds the tube part 2 and a repairing member 5 by retaining the repairing member 5 at the prescribed position and together executes the inspection after welding without pulling out an inserting body 3. |
