摘要： PURPOSE:To enhance work efficiency and workability by providing a tube exterior shield, tube interior shield and radiation source. CONSTITUTION:The device is provided with a aligning mechanism in which a radiation source 3 is held in the center of a tube 1 by means of a pantograph mechanism consisting of links 7, 9, springs 26, 34, rollers 8, 10, etc., at the tip of a flexible tube 16; also the device is constituted of the main body of a radiographic device, which is provided with a tube interior shield, and a tube exterior shield consisting of shields 19a, 19b, 17a and 17b. The exterior shield 17b is provided with a slit 43 and a radiation dose detector 18, which is fixed opposite to a tube welding part, and a film 4 is set in the whole area inside the annular groove of the exterior shields 17a, 17b. Then, by the flexible tube 16, the main body of the radiographic device is pushed inside the tube together with tube interior shields 5a, 5b. Radioactive rays from the radiation source are detected through the slit 43 by the detector 18; after the radiation source is accurately positioned in the tube welding part 2, the film position of the exterior shield is made ready; and photographing is performed by retreating the interior shield. Thus, the leakage of radioactive rays is prevented during photographing.

摘要： PURPOSE:To simplify the equipment and to perform continuous welding while positioning and traveling with high accuracy by adopting a rack and pinion system and a rotational oscillating mechanism. CONSTITUTION:An X-axis rail 4 is placed uniformly on right and left on the center of a Y-shaped notched part 2a which is made to a welded joint of rectangular sheets 1a and 1b. This is fixed parallel with a bending fold 3 between by supporting plates 6a and 6b and clampers 7a and 7b provided on both sides of the X-axis rail 4. A Y-axis fixed carriage 10 is mounted on a traveling carriage 8 fitted freely slidably on the X-axis rail 4 and a Y-axis rail 9 is made slidable in the orthogonal direction to an X-axis. A Z-axis 11 to move vertically for the weld face is fitted so as to oscillate freely at the tip of the Y-axis rail 9. A rotational oscillating axis 13 to support a welding torch 12 is arranged on an slide plate of the Z-axis 11. Two eccentric shafts are fitted in a holder to hold the torch 12 and the torch 12 is allowed to execute oscillation of a circular motion with a specified radius without making rotation. Consequently, the part which has been depending on manual welding can be automated.

摘要： PURPOSE:To weld thin sheets having flat parts and arc-shaped bulging parts automatically with high efficiency and high quality by moving a welding torch reverse around the perpendicular axis so as to make the angle of inclination thereof constant in the state when the welding torch descends toward the bulging parts. CONSTITUTION:A welding torch 34 is beforehand inclined with respect to a swiveling shaft 32, and when the torch arrives at a bulging part 41, the torch begins to weld the weld zones. A servocontrol motor 25 runs on changing of the arc voltage and a welding head 24 begins to ascend. Then a position detector 28 decelerates a motor 19 for traveling, thus maintaining the welding speed constant. At the same instant when the torch 34 arrives at the peak of the part 41, an air cylinder 37 operates to turn the torch 34 around the shaft 32 at a right angle to the advancing direction of welding with the plane inclusive of the peak and perpendicular to a flat part 13 as a symmetrical plane. In this state the torch 34 continues to descend and when the torch arrives at the transfer point 43 to the part 13, the air cylinder 37 operates to turn the torch 34 to the original inclined state, thus the welding in the weld zones of the part 13 is accomplished continuously.

摘要： PURPOSE:To cut and remove a plate of a welding joint part by comparatively small cutting reaction by boring successively plural holes having a depth corresponding to a wall thickness of the plate in the welding parts while leaving narrow partition walls, and cutting the partition walls between the adjacent holes by a tool. CONSTITUTION:A plate 3 is connected between left and right vacuum container bodies 1 through the welding parts 4, and a welding joint part is formed. When this welding joint part is cut, in the first place, holes having a depth corresponding to a thickness of the plate 3 are bored in the left and right welding parts 4 by using drills 5 and 6. The respective holes 7 are bored successively while leaving partition walls of several mm. Next, these partition walls are cut by a glider, and the plate 3 is removed. A plate on the side of this outside surface is removed similarly, and the welding joint part between the left and right vacuum container bodies 1 is cut.
