摘要： The present invention relates to a method for manufacturing a secondary battery and a secondary battery manufactured by using the manufacturing method, and more particularly, to a method for manufacturing a secondary battery, in which, when a thin film can is welded, a bonding portion is improved in adhesion to prevent an non-welded portion from occurring, thereby remarkably improving sealing properties, and a secondary battery manufactured by using the manufacturing method. A method for manufacturing a secondary battery according to the present invention comprises: a welding preparation process of preparing a lower can comprising an accommodation part in which an electrode assembly is accommodated, and an upper cover covering an upper opening of the lower can; a gripping process of gripping an end of a lower can circumferential portion and an end of an upper cover circumferential portion at upper and lower portions by using an upper jig and a lower jig in order to weld the lower can circumferential portion that is a portion extending outward from an edge of the accommodation part to the upper cover circumferential portion that is a circumferential area of the upper cover; and a welding process of irradiating laser onto a bonding portion that is a point, at which the lower can circumferential portion and the upper cover circumferential portion are bonded to each other, to bond the lower can circumferential portion to the upper cover circumferential portion through laser welding. In addition, in the secondary battery according to the present invention, a bonding portion that is a point at which the lower can circumferential portion and the upper cover circumferential portion are bonded to each other has a height lower than a height (b) of the accommodation part.

摘要： A laser welding device includes: a laser oscillator with which an incoming end of a fiber is connected; a welding head that is connected to an outgoing end of the fiber and that performs laser welding while irradiating a workpiece with laser light by guiding the laser light from the laser oscillator to the workpiece via the fiber; a sensor that detects, during the laser welding, an intensity of plume light that is based on the laser welding at a welded position at which the workpiece is irradiated with the laser light; and a controller that controls a height of the welding head based on a detection output from the sensor, the height being a height in a direction parallel with a direction that the laser light is emitted.

摘要： Verfahren zur Herstellung eines Aktivteils (1) für eine rotierende elektrische Maschine (101), umfassend folgende Schritte:
- Bereitstellen eines Kerns (2) für das Aktivteil (1) und in den Kern eingesetzter Formleiter (6), wobei der Kern (2) eine Stirnseite (3), eine der Stirnseite (4) gegenüberliegende weitere Stirnseite (4) und mehrere in Umfangsrichtung angeordnete Nuten (5), in denen die Formleiter (6) angeordnet sind, aufweist, wobei sich die Formleiter (6) von der Stirnseite (3) zur weiteren Stirnseite (4) erstrecken und jeweils ein freies Ende (7) aufweisen, welches an der Stirnseite (3) herausragt und eine Endfläche (9) aufweist;
- Aneinanderfügen von jeweils zwei der Endflächen (9), sodass die zwei Endflächen (9) ein Paar (10) bilden; und
- Verschweißen eines jeweiligen Paars (10) der Endflächen (9) mittels eines Laserstrahls, der auf den Endflächen (9) des Paars (10) entlang einer ersten Trajektorie (13) und einer zweiten Trajektorie (14) geführt wird, wobei die erste Trajektorie (13) und die zweite Trajektorie (14) jeweils einen Anfangspunkt (13a, 14a) und einen davon unterschiedlichen Endpunkt (13b, 14b) aufweisen, wobei die erste Trajektorie (13) und die zweite Trajektorie (14) zwischen dem Anfangspunkt (13a, 14a) und dem Endpunkt (13b, 14b) konkav verlaufen-

摘要： The objective of the present invention is to provide a mixed powder production method, a mixed powder production device, an additive manufacturing method, and an additive manufacturing device, with which a plurality of types of powders can be accurately and quickly mixed in a desired mixing ratio. This mixed powder production method uses a plurality of types of powders as a raw material, and has: a first step, in which a plurality of raw material powder supply passages, which are provided respectively for each of the plurality of types of powders, are used to pressure-feed the plurality of types of powders to a gap space; a second step, in which the pressure-fed plurality of types of powders are sprayed into the gap space, which has a cross-sectional area larger than the total of the cross-sectional areas (the total cross-sectional area) of the plurality of raw material powder supply passages, thereby mixing the plurality of types of powders and obtaining a mixed powder; and a third step, in which the mixed powder is discharged from a discharge opening provided downstream from the gap space.
