摘要： PROBLEM TO BE SOLVED: To provide a dissimilar metal welded tube having superior machining performance in hydroforming and also to provide its manufacturing method.
SOLUTION: This is a dissimilar metal welded tube for hydroforming, and the tube has different thickness and/or tensile strength in the tube axis direction. While a weld line formed with the end faces of metallic materials having the same thickness and/or tensile strength shows a straight line parallel to the tube axis, a weld line formed by butt welding or lap welding with metallic materials having different thickness and/or tensile strength shows a spiral shape inclined 45-75 degrees to the tube axis in the dissimilar metal welded tube for hydroforming.

摘要： PURPOSE:To easily and surely detect the break of the bulged part by detecting the pressure of the die space between the upper die and the lower with the sensor on the time that the non-cladded part of the laminated sheets is bulged with the pressurized air while clamping the laminated sheets with the upper die and the lower die. CONSTITUTION:The laminated sheets W for manufacturing the roll bond panel is clamped between the upper die 11 and the lower die 12 through the annular packing 13. And the primary air for pressing the laminated sheets is supplied to the space inside the die 14 of the lower side of the laminated sheets W, the laminated sheets W is pressed to the down surface of the upper die 11. In this state, the secondary air for bulging is supplied to the non-cladded part of the laminated sheets W, only the non-adhered part of the lower side of the laminated sheets is bulged. In this time, the pressure of the space inside the die 14 is detected with the sensor 15, if the pressure is made larger than the prescribed value, it is judged that the break B is generated on the bulged part. Therefore, the break of the bulged part of the roll bond panel can be detected easily and surely.

摘要： PURPOSE: To turn the residual tensile stress of the inside surface of a joint to compressive stress and prevent stress corrosion cracking by solidifying and expanding the material sealed in the inside by cooling means disposed in the welded joint part or on the outer circumference of both sides then melting the same.
CONSTITUTION: A material which turns solid and expands when cooled, for example, water 4, is packed in piping. Next, cooling means 5, 5' are disposed on the outer side on both sides of a welded joint part 3, the water 4 is cooled. Then, the water near the inside circumference of the means 5, 5' is cooled to ice and ice plugs 6, 6' are formed. Further when the cooling by the means 5, 5' is continued, the plugs 6, 6' grow gradually so that the internal pressure of the water 4 confined by the plugs 6, 6' is boosted. The pipe diameter is expanded by the internal pressure thereof, whereby a plastic deformation is caused in the joint part 3 and near the same. When the cooling is ceased after the initiation of the plastic deformation and the plugs 6, 6' are melted to release the internal pressure of the water 4, the residual tensile stress in the part 3 turns to compressive stress.

摘要： PROBLEM TO BE SOLVED: To provide a tailored steel pipe excellent in a hydroform workability by restraining the lowering the workability of a welding part in the circumferential direction and its producing method. SOLUTION: When the tailored steel pipe for hydroform working is produced by connectively welding a plurality of steel pipes 1, 2 with the welding in the circumferential direction, the hydroform workability at the welding part is improved by lapping the started and the finished end parts of the welding in the circumferential direction desirably over the range of 5° -25° of center angle θ. The hydroform workability can further be improved by adding a softening process for applying the heat treatment to the welded part. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a superelastic molding method capable of making the plate thickness distribution of a molding optimum. SOLUTION: By mutually welding the rims of a thick raw plate 1a and thin raw plates 12b, 13b, a tailored blank 1 is formed, and it is clamped with a female mold 402 and a block 403. When a pressure is applied to the tailored blank 1 at the predetermined temperature, the raw plate 1a is subjected to superelastic deformation to be stretched, and pushed to the bottom face 4022 of the female mold 402. Thereby, a bead with a thick bottom can be manufactured.
