Abstract: Provided is a friction stir spot welded joint having high joint strength even in the case where a high strength steel sheet, particularly a steel sheet with a tensile strength (TS) of 980 MPa or more, is used as a material to be welded. An annular groove is formed on an upper surface of an upper sheet out of overlapping steel sheets, and a shape, microstructure, and hardness of a welded portion are appropriately controlled simultaneously.

Abstract: A laser welding method for irradiating a plurality of stacked metal plates in an upright position with a laser beam to weld the plurality of stacked metal plates is provided. The laser welding method includes irradiating the plurality of metal plates with the laser beam to form a circular molten pool and scanning the laser beam once around an outer periphery of the molten pool to enlarge the molten pool. In the enlarging of the molten pool, a scanning start point of the laser beam is set within a range from 135 degrees to 315 degrees in a scanning direction of the laser beam, with 0 degrees directly above the molten pool in a vertical direction.

Abstract: in a method for producing a solder deposit in a metal sheet, a depression is made in a topside of the metal sheet through deep drawing, thereby causing material to protrude on a bottom side of the metal sheet. The metal sheet is then subjected to a material forming process to produce a collar such that the collar projects in relation to the topside. The collar is then at least partially pressed in a direction of the depression to reduce a cross-sectional area of a mouth of the depression, and the protruding material on the bottom side is completely pushed back so that the bottom side in a region of the depression is in one plane with neighboring regions of the bottom side.

Abstract: A gas shielded arc welding method includes welding a steel sheet with a tensile strength of 780 MPa or more using a shielding gas containing Ar in an amount of 92 vol. % to 99.5 vol. %. In the gas shielded arc welding method, a value calculated from the following expression (1) is 0.20 or more: {√v/(D/2)2}×10−{(100−CAr)×I/v}×0.1 . . . (1), where CAr represents an Ar content (vol. %) in the shielding gas, D represents an inner diameter (mm) of a nozzle from which the shielding gas is supplied, v represents a welding speed (cm/min), and I represents a welding current (A).

Abstract: A method for welding between two metallic plates, including:



(a) fitting a solid plate without openings, configured to be transparent at at least one emission wavelength of a laser beam (F) emitted by a laser (L), between the laser (L) and at least one contact zone between the metallic plates to be welded;
(a1) inerting of the contact zone via a netural gas, where the neutral gas circulates in channels delimited by the contact zone between the metallic plates and by the solid plate;
(a2) exerting pressure on the two metallic plates to apply them against one another in the contact zone to be welded, where the application pressure is exerted by the solid plate directly in contact with one of the two metallic plates to be welded; and
(b) emission of a laser beam, through the solid plate, to perform welding of the metallic plates in the contact zone.

Abstract: A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.

Abstract: Proposed is a resistance spot welding method to join parts to be welded which are a plurality of overlapping metal sheets, including: dividing a current pattern into two or more steps for welding; before actual welding, performing test welding; and subsequently, as actual welding, performing adaptive control welding, in which the two or more steps for welding include a step of securing a current path between the sheets directly below the electrodes and a subsequent step of forming a nugget having a predetermined diameter, and a welding interval time is provided between these steps. This method thus yields a good nugget without causing splashing even under special welding conditions.
