A laser welding method is provided to ensure a sufficient joining strength between metal plates by increasing the area of a joining region while preventing 'burn through' of a molten metal. In the laser welding method by applying a laser beam to a surface of multiple metal plates superimposed on each other, a scanning locus with the laser beam is sequentially shifted from an inner circular scanning locus to an outer one in a predetermined joining region on the metal plates, and an emission interval is provided to temporally stop the metal-plate-surface irradiation when the scanning locus is shifted. Thus, every time the scanning locus is shifted, the molten metal due to the previous irradiation is cooled and increases its viscosity. Accordingly, the 'burn through' is prevented regardless of increase of the area of the joining region, which results in a sufficient joining strength between the metal plates.

In a laser welding method, generation of relatively large blow holes in a welding part is prevented while decrease in productivity is reduced. The laser welding method for lap welding, using a laser beam LB, of a plurality of metal plates and including an aluminum alloy cast plate includes: a melting path of scanning and irradiating circularly a superimposed part of the aluminum alloy plate and the aluminum alloy cast plate with a first laser beam LBto form a molten pool of the molten aluminum alloy plate and the molten aluminum alloy cast plate; and a stirring path of scanning and irradiating circularly the molten pool with a second laser beam LBhaving a scanning speed Vfaster than a scanning speed Vof the first laser beam LBto stir the molten pool.

An electrode tip portion is provided with a projection portion and a plurality of recess portions. The plurality of the recess portions are independent of one another, and are provided at the electrode tip portion in a dispersed manner. The projection portion is a region other than regions where the recess portions are provided, and is configured to be equipped with a continuous surface that continues in regions among the plurality of the recess portions.

Electrode for resistance spot welding

An information processing device includes a control unit configured to perform: acquiring a degree of congestion of persons that are located in a predetermined range including a plurality of vehicles which is parked at predetermined positions and is able to travel autonomously; determining a positional relationship between the plurality of vehicles based on the degree of congestion; and transmitting a movement command to a first vehicle which is a vehicle which is requested to move out of the plurality of vehicles such that the determined positional relationship is satisfied.

Information processing device, vehicle position control system, and vehicle position control method

An information processing device includes a control unit that executes: acquiring information indicating an environment surrounding a place where a plurality of movable objects is disposed, the plurality of movable objects including display units that display a picture to configure an external appearance; deciding a display content of the picture to be displayed by the display units included in the plurality of movable objects, depending on the information indicating the environment surrounding the place; and giving an instruction to cause the display units to display the picture having the decided display content, to the plurality of movable objects disposed at an area surrounding the place.

Information processing device, information processing method and program

Provided are a method and an apparatus for resistance spot welding in which preliminary current application is executed and then main welding is executed in accordance with master patterns of various parameters obtained during the preliminary current application. The main welding is executed under welding conditions of the master patterns, and whether a welding abnormality has occurred and whether the welding abnormality is likely to occur are determined. When the welding abnormality is likely to occur, the welding conditions for the main welding are corrected so as to prevent the welding abnormality. When the welding abnormality is unlikely to occur, the welding conditions for the main welding are corrected so as to match the master patterns.

Resistance spot welding method and resistance spot welding apparatus

Partial welding of partially joining together two metal plates by melting at least one area inside a joining region of the metal plates is performed. After a lapse of a predetermined time from completion of the partial welding, main welding of joining together the metal plates by melting the joining region entirely is performed.

Welding method

A resistance spot welding method includes sandwiching metal plates put on top of one another between a pair of electrodes and performing resistance spot welding sequentially on a plurality of welding points close to each other on the metal plates by performing a current application between the electrodes so as to join the metal plates to each other. A welding current value to form a welding nugget at a welding point to be subjected to the resistance spot welding second or later among the welding points is set to be higher than a first welding current value to form a first welding nugget at a first welding point to be subjected to the resistance spot welding first among the welding points.

Resistance spot welding method

An audio device includes a first broadcast processor configured to execute reception processing of a first broadcast wave to generate a first reproduction signal, a reproduction unit configured to reproduce audio based on the first reproduction signal, a first storage configured to temporarily store audio data related to the first reproduction signal, a controller configured to acquire a time table of a broadcast related to the first broadcast wave and receive a saving instruction of a musical piece from a user, and a second storage configured to, when the controller receives the saving instruction, cut first musical piece data of a predetermined musical piece depending on a reception time of the saving instruction from the audio data temporarily stored in the first storage based on the time table and store the first musical piece data.
