摘要： The present disclosure provides a joining technique capable of improving strength and reducing electrical resistance of a connecting portion that performs heterometal interjunction in a sealed battery. A mode of the sealed battery disclosed herein includes an electrode body, a battery case, a positive electrode internal terminal, a positive electrode external terminal, a negative electrode internal terminal, and a negative electrode external terminal. In the sealed battery, in a connecting portion between the negative electrode internal terminal and the negative electrode external terminal, an upper end of the negative electrode internal terminal and the negative electrode external terminal are stacked with a plated layer interposed therebetween and, at the same time, the negative electrode internal terminal and the negative electrode external terminal are joined to each other via the plated layer. In addition, a rough surface having a plurality of recessed portions is formed on the upper surface of the negative electrode external terminal having been stacked with the plated layer interposed therebetween, and a part of the plated layer penetrates into the recessed portions. Accordingly, a connecting portion having high strength and low resistance can be formed between the negative electrode internal terminal and the negative electrode external terminal.

摘要： A laser welding method and a laser welding apparatus capable of preventing formation of blowholes and obtaining an excellent welled state are provided. An embodiment is a laser welding method for a component to be welded 40 including a third metal component 40c sandwiched between first and second metal components 40a and 40b, in which the metal components are welded to each other by scanning a laser beam in a first direction perpendicular to a direction in which the third metal component 40c is sandwiched, in which a welded part 42 is formed by applying a first laser beam 12a while scanning it in the first direction and thereby melting and then solidifying the component to be welded 40.

摘要： A torsional vibration reduction device provided inside a torque converter includes rolling elements, a plate, and a cover. The plate includes rolling chambers housing the rolling elements. The cover encloses and shields the rolling elements and the plate from a working fluid surrounding the torsional vibration reduction device inside the torque converter. The cover includes first and second covers that are joined together with the plate held between the first and second covers. The first and second covers contact the plate in an axial direction of the torque converter at locations that are, with respect to an axis of the torque converter, on an inner peripheral side and on an outer peripheral side of the rolling chambers. Surfaces of the first and second covers are joined to the plate at least at part of the locations where the first and second covers contact the plate.
