A method of production of a welded structure by butt welding two steel sheets (51, 52) by laser welding (11) while supplying assist gas (12) to a back surface of a melt pool (13), whereby it is possible to prevent formation of a through hole in the melt part (53), characterized in that a thickness of at least one steel sheet (52) of the two steel sheets (51, 52) is 0.6 mm or less, the assist gas (12) is a mixed gas (12) containing 10 to 50 vol % of O.sub.2 gas, and, when an O.sub.2 concentration in the mixed gas (12) is C (vol %), a flow rate L of mixed gas (12) (liter/min) satisfies 30 (liter/min)C(vol %)1 (liter/min/vol %)L (liter/min)<40 (liter/min).

A method of assembling a vehicle component, a system for assembling a vehicle component, and a vehicle component assembly. A blank is formed from a steel sheet, wherein the steel sheet includes a coating on a surface. The coating is removed from a first interface surface of the blank and the blank is stamped either prior to or after removing the coating. The first dynamic interface surface is arranged relative to a second interface surface and thermally joined to form a joint.

A lightweight vehicle pan assembly and for attachment to a vehicle frame via welding includes at least one metal flange and a molded pan body. The at least one metal flange has a weld portion adapted for welded attachment to the vehicle frame and an interface portion extending from the weld portion. The molded pan body has a base wall and at least one side wall extending upward from the base wall. The interface portion of the at least one metal flange is embedded in the at least one side wall of the molded pan body. The interface portion includes at least two rows of apertures defined therein for increasing a bond strength between the at least one metal flange and the molded pan body.

A method includes forming a first pocket in a first sheet of material and a second pocket in a second sheet of material, pressing the first pocket and the second pocket together at a nonlinear interface, and welding material of the first pocket and the second pocket at the interface.

A method for manufacturing a tailored blank press formed product includes a tailor welding step in which a first steel plate and a second steel plate are abutted against each other and welded together at side surfaces thereof to form a blank; a shearing step of shearing the blank or a first intermediate product, which is a processed blank, along a line that crosses a welding line formed in the tailor welding step; and an electric heating step of electrically heating a welded-and-sheared portion of a sheared section of the blank or the first intermediate product, the welded-and-sheared portion being welded in the tailor welding step.

A vehicle pillar structure and a method for manufacturing a vehicle pillar in which, in a pillar framework, a member is easily disposed on a surface facing a transparent panel in an overlapping manner, while reducing the width of the pillar framework, and a corner butt portion on the side of the transparent panel has increased welding accuracy are provided. A flange of an outer panel and a flange of an inner panel are welded by spot welding. An end surface of a front end of the inner panel is butted against an inner surface end of the outer panel, and is welded thereto by laser welding, such that welding beads are thereby linearly formed at established intervals.

Provided is a welding method that can enhance joining quality between an upper plate and a lower plate. One aspect of the present disclosure is a joining method including joining the upper plate to the lower plate that is overlapped with the upper plate by applying energy to a top surface of the upper plate to thereby melt the upper plate and the lower plate together. A joining path designed to apply the energy to the top surface of the upper plate crosses an axis along a joining-travel direction and includes a turn-point. An amount of the energy includes a first energy applied in the vicinity of the turn-point and a second energy amount applied in an area other than the vicinity of the turn-point. The first energy amount is smaller than the second energy amount.

In order to further improve a method for joining a multilayer component (10) to another component (11) in a way that allows the multilayer component (10) to be mechanically and electrically joined to other elements, it is provided that an intermediate layer (14) of the multilayer component (10) be displaced in the region of the joining site (32), and that the two outer structural elements (12, 13) of the multilayer component be joined to one another by applying an electric voltage; and that the other component (11) be joined as a fastening element to the multilayer component (10) in the region of the joining site (32).

According to an exemplary embodiment of the present disclosure, disclosed is an aluminum coated blank that includes a first coated steel sheet; a second coated steel sheet connected to the first coated steel sheet; and a joint portion that connects the first coated steel sheet to the second coated steel plate at a boundary between the first coated steel sheet and the second coated steel sheet.
