摘要： PROBLEM TO BE SOLVED: To provide a structure reforming method which surely prevents the surface of a casting and a casting defect from being communicated with each other. SOLUTION: A rotary tool 20 having a base part 31, and a projecting part 32 extending by inclining from a front end 31a in an axial line direction of the base part 31 in a direction approaching a rear end 31b in the axial line direction as the projecting part protrudes in the radial direction of the base part 31 and progresses in one R1 of the peripheral direction around the rotary axis L1 is used to conduct friction stirring by rotating the rotary tool 20 in the one R1 of the peripheral direction. Thereby a fluid 38 with a softened part plastically flowing is formed in a prepared hole 36. The fluid 38 moves in the rotating direction R1 and also in the axial line direction Z1 and thereby the fluid 38 is made easier to stir and the amount of the fluid 38 plastically flowing can be increased. As a result, the fluid 38 can increase the solidified reforming layer 39 and can increase the amount of dissipation of the casting defects, and the inner peripheral surface of the prepared hole of the casting 19 is more surely prevented from being communicated with the casting defect.

摘要： PROBLEM TO BE SOLVED: To provide a deformation estimating method capable of estimating weld deformation under constraint.
SOLUTION: In a step S7, an intrinsic strain under constraint, that is an intrinsic strain θ
V of lateral bend angle deformation, is obtained. The intrinsic strain is, based on the information of intrinsic strain under constraint, which is sought by experiments or the like and stored in an intrinsic strain database, determined by the following: a plate thickness h, a joint type, and a welding length L, which are designated in a step S2; a welding method, a welding heat input Q
0 , and a material, which are designated in a step S3; and a degree of bending constraint K
B calculated in a step S6. In a step S8, a state that a constraining tool is released is modeled and an elastic finite-element analysis is conducted. At that time, weld deformation analysis is conducted in a step S9 based on: an intrinsic strain g
x of longitudinal contraction, an intrinsic strain g
y of lateral contraction, and an intrinsic strain θ
x of longitudinal bend, which are obtained in a step S4; and an intrinsic strain θ
v of lateral bend angle deformation, which is obtained in the step S7. Thus, in a step S10, the weld deformation of a weld structure is estimated in consideration of the influence of constraint.

摘要： PROBLEM TO BE SOLVED: To provide a rotary arc welding device which enables to effectively control a vibration caused by a precession of an electrode, and to make itself small and light weight. SOLUTION: One end of the electrode 2 is supported by an automatic aligning ball bearing 9 as a fulcrum and the middle part of the electrode 2 is supported by an eccentricity rotary unit 10. The eccentricity rotary unit 10 is rotated to activate the electrode 2 a precession, and a power feeding tip 5 at the end of the electrode 2 a circular motion around a rotational center 14. To a welding wire 28, which penetrates through the inside of the electrode 2, a welding electric current is fed from an electric feeding cable 7 so that the arc at the tip of the welding wire 28 conducts a welding by rotating the arc. The eccentricity rotary unit 10 is equipped with a heavy weight part 18 at an opposite position to the supporting point of the electrode 2, to control a vibration energy from the precession of the electrode 2, with reference to the rotational center 14. By doing so, a force of inertia about the rotational center 14 can be balanced and the vibration energy is controlled.

摘要： PROBLEM TO BE SOLVED: To automatically calculate the off-seam quantity of a two side butt welding part by removing by grinding the reinforcement of the weld bead from an end part by the prescribed length, and extracting the toe line of the weld bead from the radiographic image including the reinforcement ground part. SOLUTION: The reinforcement of a bead 3 on the inner surface side of a tubular end part of a welded tube 1p is removed by grinding from a tube end by the prescribed length. The radiographic image of a part 9 to be inspected is taken into an image processing computer 15 as the digital image through an image processor 11 and an analog-digital converter 14, and formed as an original image. The lightness of the original image is normalized by the image processor 15, and the noise is removed to perform the binarized image processing. Presence/absence of a boundary part between a reinforcement ground part and a non-ground part is detected, and the center line of the reinforcement of the weld bead which is not ground yet is extracted. After the positional relationship of the toe line is determined, the off-seam quantity is calculated, and compared with the off-seam quantity which is statistically processed in advance to judge acceptance/rejection of the welding quality.

摘要： PURPOSE:To prevent the noise echo generated by the reflection of the ultrasonic wave on the outer periphery of a wave guide rod from being increased and clearly detect the primarily necessary echo reflected by a flaw in a specimen with a probe. CONSTITUTION:Many independent fine recesses 18 or projections or a mixture of recesses and projections are formed in the region of the outer periphery near the contact face 16 of a wave guide rod 12 brought into contact with a specimen 19. The ultrasonic wave transmitted from a probe 13 is reflected by a flaw in the specimen 19, and the returned echo is received via the wave guide rod 12. The noise echo is suppressed by the recesses 18 and/or projections formed on the wave guide rod 12, and the flaw of the specimen 19 can be detected with high detection accuracy.
