Abstract: Provided is a method of welding laminated metal foils that can prevent blowholes and spatter from being formed. It is a method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates. The method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates includes locally pressing and crimping the laminated metal foils sandwiched between the pair of metal plates at a welding point in a laminating direction, and welding the crimped pair of metal plates and laminated metal foils at the welding point.

Abstract: A laminated structure is manufactured using a mold in which an injection port is provided, the laminated structure including a core layer, a first surface layer, and a second surface layer. The mold includes a first surface layer material conveyance path through which a raw material of the first surface layer is conveyed, a second surface layer material conveyance path through which a raw material of the second surface layer is conveyed, and a core layer material conveyance path through which a raw material of the core layer is conveyed. The paths merge at the injection port. The mold has a shape in which a downstream portion downstream of a merging location that is the injection port does not contact the injected laminated structure formed of the raw materials. The laminated structure is injected by causing viscous fluids as the raw materials into the paths, respectively.

Abstract: 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.

Abstract: Provided is a winding device capable of speeding up a winding operation while ensuring a winding quality. A feed roller feeds a sheet-like member. A take-up roller takes up the sheet-like member. Each roller guides transportation of the sheet-like member between the feed roller and the take-up roller. A sum of moments of inertia of each free roller is determined so that a variation in a tension applied to the sheet-like member is equal to or less than 16.7 [N/m].
