The first and second metal members, and the auxiliary member are made of aluminum or an aluminum alloy, and the first and second metal members have higher hardness than the auxiliary member. At least one of the first and second metal members has an inclined surface inclined outward, and the auxiliary member has an inclined surface, tapered from the external surface toward an internal surface, on at least one of the side surfaces.

A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.

A method of forming a sealed canister and a method of storing radioactive materials is provided. The method of forming includes placing a top plate on a top opening of a side wall, a bottom of the side wall being sealed to a base plate. The top plate includes a top surface with a top edge having a bevel and with a channel set in from the top edge. Finally, a weld is formed between the beveled top edge and the top opening of the side wall to seal the top plate to the side wall.

A metal assembled body including a first member formed by forging a metal material, the first member including a peripheral wall portion in which a metal flow is formed along an axial direction and an extending portion extending from the peripheral wall portion and having an opening, the peripheral wall portion and the extending portion being formed integrally, and a closing member welded to a welding surface on the extending portion to close the opening, before the closing member is welded, the extending portion being formed to expose an end portion of the metal flow at the welding surface, and a welding position of the closing member on the welding surface being set to make a width of a first region larger than a width of a region excluding the first region, the first region being a region divided by a welding site, where arrival of a gas is inhibited.

A marking device, a medium, a container, and a marking method. The marking device includes a first marker including a first optical system having a first focal point, the first marker being configured to concentrate a first light onto a first area of a non-planar portion of a medium to perform marking on the first area, the non-planar portion including a plurality of areas including the first area and a second area, and a second marker including a second optical system having a second focal point. The second marker is configured to concentrate a second light onto the second area to perform the marking on the second area, and the second focal point of the second optical system is different from the first focal point of the first optical system in a direction parallel to a central axis of the first optical system.

The invention relates to a profile in a container, where a profile (5, 6, 7, 8, 101) comprising a cross section where at least a part of the cross section over a length of the profile is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the critical buckling load for zones abutting the crumple zone. The invention further relates to a method of manufacturing a profile for a container, where one or more profiles (5, 6, 7, 8, 101) in the container (1) is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the rest of the profile (5, 6, 7, 8, 101). The invention also relates to abase structure for a container, comprising a pair of bottom side rails, a front sill (4) in one end and a door end in an opposite end, a number of crossmembers (8) placed in parallel with the front sill (4) and door end and extending from a bottom side rail (2) in one side of the container (1) to a bottom side rail (2) at the other side of the container (1), wherein the crossmember (8) comprises a cross-section, where at least a part of the cross section over a length of the profile (5, 6, 7, 8, 101) is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the critical buckling load for zones abutting the crumple zone.

A welding material may be suitable for high-Cr ferritic heat-resistant steels, and may suppress δ-ferrite occurrence, i.e., a soft structure, thereby improving the toughness, and enabling the achievement of a welded metal that has good cracking resistance and strength at high temperatures. Such welding materials for high-Cr ferritic heat-resistant steels may contain C, Si, Mn, S, Co, V, Nb, W, N, and O, respectively within specific ranges and limits Ni and P respectively to specific ranges, while containing from 8.0% by mass to 9.5% by mass (inclusive) of Cr and from 0.02% by mass to 0.20% by mass (inclusive) of Mo and additionally limiting Cu to less than 0.05% by mass, with the balance being made up of Fe and unavoidable impurities.
