摘要： This arc spot welding method for dissimilar materials joins a steel upper plate and a non-ferrous metal lower plate. The upper plate has a flat plate-like base part and an upright wall part erected on the base part. The base part has a through-hole. The arc spot welding method for dissimilar materials includes superposing the base part on the lower plate so that the lower plate faces the base part via the through-hole; and arc-welding the base part and the lower plate by filling the through-hole with a molten weld metal at a position, which is a target position, offset in the direction opposite the upright wall part from the center of the through-hole.

摘要： The element joint is obtained by joining: a long pipe; a short pipe made of a quality of material having a strength equal to or higher than a strength of the long pipe; and a plate material made of a quality of material having a strength equal to or higher than a strength of the short pipe. In the element joint, at least one member of the long pipe and the short pipe includes a pipe-shaped portion, and the pipe-shaped portion of the one member is pipe-expanded and joined to the other member by press-fitting. The short pipe and the plate material are welded to each other.

摘要： An extruded material includes a peripheral wall having a closed loop-shaped cross-section and defining a hollow, and a middle rib connected to an inner peripheral surface of the peripheral wall and dividing the hollow. The extruded material is provided with a corrected portion set at a predetermined portion in a longitudinal direction and subjected to correction processing, and an uncorrected portion not subjected to the correction processing. The peripheral wall is expanded outward with respect to an original shape of the uncorrected portion in the corrected portion. While the middle rib is curved with respect to an imaginary straight line connecting connecting portions connected with the peripheral wall at both end portions of the middle rib in the uncorrected portion, the middle rib has a smaller degree of curvature than the original shape of the uncorrected portion in the corrected portion.

摘要： A high-strength hot-dip galvannealed steel sheet may include a plating layer on a surface of a base steel sheet. The base steel sheet may satisfy a predetermined chemical composition, in a metallographic structure of the base steel sheet, wherein a volume ratio of martensite (including tempered martensite and self-tempered martensite) is 82 vol % or more, a volume ratio of ferrite, pearlite and bainite is 13 vol % or less in total, and volume ratio of retained austenite is 5 vol % or less, in an image obtained by observing the metallographic structure of the base steel sheet with a scanning electron microscope, the number of laths at a total length of 300 μm, the number being measured by an intercept method is 200 or more, a yield strength is 970 MPa or more, and a tensile strength is 1,470 MPa or more.

摘要： In a suspended industrial robot, a base and a swivel section have an internal space into which a cable can be inserted. The base has an insertion opening through which at least the cable can be passed into the internal space from the outside. A first cable holding part that holds the cable is installed on at least one of a first arm and a second arm. The cable passes through the internal space of the base and the swivel section and is routed up to an end effector with a midway portion of the cable being held by the first cable holding part.

摘要： A seat back frame for automobile includes a first side frame and a second side frame that are arranged apart from each other in a vehicle width direction, an upper frame that connects an upper end portion of the first side frame and an upper end portion of the second side frame, and an upper bracket that is attached to the upper end portion of the first side frame and guides a seat belt. The first side frame is an extruded material extending in a vehicle vertical direction, and has a fixed lower end portion. The first side frame has a closed cross-section portion in a cross-section perpendicular to the vehicle vertical direction. The upper end portion of the first side frame is crushed rearward of a vehicle, and a thickness of the upper end portion in a vehicle front-rear direction is smaller than that of the lower end portion.
