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.

A secondary battery includes: an electrode body including an electrode main body, a collector foil protrusion section, and a collector foil connection portion; a first collector terminal including a first extension part that is welded to the collector foil connection portion; and a second collector terminal that is a member separate from the first collector terminal and includes a second extension part welded to the collector foil connection portion. The first extension part and the second extension part are located on the opposite sides of the collector foil connection portion. The secondary battery includes a welded joint at which both the first extension part and the second extension part are welded to the collector foil connection portion such that the first extension part, the second extension part, and the collector foil connection portion are united. The first collector terminal and the second collector terminal are united through the welded joint.

A method for edge-to-edge welding of a first sheet metal panel to a second sheet metal panel on a bearing structure. The method comprises positioning and fixing the first panel to the bearing structure, positioning and fixing the second panel to the bearing structure with the second panel overlapping a raw edge of the first panel, jointly cutting the first panel and the second panel in the overlap area to form a connection edge of the first panel and a connection edge of the second panel, withdrawing scrap cuttings from the first panel and scrap cuttings from the second panel, and friction stir welding the connection edges.

A method is provided for the remote laser welding of two coated sheets, wherein by way of a scanner, a laser beam is directed at the sheets to be connected to each other and guided on the sheets. The sheets are connected to each other by producing an end fillet weld on a lap joint. The continuous production of the weld is recorded by a camera and, if necessary, the path of the laser beam is corrected and adapted to a target weld course on the basis of an automatic evaluation of the recorded images.

When a first sub-controller (14) and a second sub-controller (15) complete preparation for control, a preparation completion signal is sent to a main controller (13). When receiving the preparation completion signal from each of the first and the second sub-controllers (14)(15), the main controller (13) sends a BusyON signal to the first sub-controller (14) and the second sub-controller (15), and then drives a laser source (16) to generate laser light L. Then the main controller (13) sends a BusyOFF signal to the first and the second sub-controllers (14)(15). When the first sub-controller (14) receives the BusyON signal and then receives the BusyOFF signal, the first sub-controller drives a laser-light irradiation unit (17). When the second sub-controller (15) receives the BusyON signal and then receives the BusyOFF signal, the second sub-controller drives a moving mechanism (12).

A vehicle reinforcement beam is roll formed from a metal sheet to provide a multi-tubular reinforcement beam that includes two adjacent tubular sections that share a common center wall. The outer sections the metal sheet extend from opposing ends of the common center wall and are formed to enclose the adjacent tubular sections. An edge portion of the metal sheet that is bent to have a bend radius of about 3-9 mm, where the edge portions attach in abutting and continuous contact with the common center wall to form crevices between the adjacent tubular sections along the first and second faces. A weld is formed in each of the crevices to define crevice ribs in general alignment with and at each of the opposing first and second ends of the common center wall that are configured to improve bending strength and torsional strength of the reinforcement beam.
