Abstract: Provided is a method of welding a shaft and a wheel in a turbine shaft. A target surface with a hole is provided to any one of the shaft and the wheel. An opposed surface is provided to the other one of the shaft and the wheel. The opposed surface includes an opposed portion opposed to the target surface, and a non-opposed portion formed continuously from the opposed portion toward a center side while facing onto the hole. The welding method includes: disposing the target surface and the opposed surface such that the they are opposed to each other while establishing a state of surface contact; and welding them by beam irradiation from outside in a radial direction of the shaft toward inside in the radial direction thereof based on a condition to cause a depth of fusion to reach a position on a center side beyond the opposed portion.

Abstract: A vehicle or robot movable in the water includes a body having a first opening in its abdomen. A float is provided at the front portion of the body so that the vehicle body suspends in the water with its front portion up. A pressure reducing device is provided in the body for reducing an inner pressure of the body so as to cause the body to suctionally adhere on a wall in the water with its abdomen facing the wall. A sealing skirt is attached along the first opening formed in the abdomen so that it contacts the wall to maintain the body's inner pressure negative as the body adheres on the wall. A drive unit is also provided in the body for moving the body on the wall. The pressure reducing device includes a hose communicated with the body at its one end and a pump connected with the other end of the hose for pulling water out of the body.

Abstract: A working apparatus comprising openings formed as gondola access holes in tank web frame of a ship, a rail passed through the openings and secured to the tank web frame, a trolley adapted to travel along the rail, a hoist mounted on the trolley, and a gondola elevatably suspended from the hoist is provided. The working apparatus can transport workers or necessary articles to a working place to be inspected or repaired for carrying out the inspection and/or repair within tanks of a ship.
