摘要:
The present invention relates to a method of welding an upper rail of a seat track for vehicle seat and adapter bracket for supporting a seat frame, the method comprising: contacting surface-to-surface a lower surface of a planar coupling surface part which constitutes a lower end part of the adapter bracket and extends in a longitudinal direction to a predetermined length onto an upper surface of a planar horizontal surface part which constitutes an upper end part of the upper rail and extends in the longitudinal direction; and joining the coupling surface part and the horizontal surface part by welding a lower surface of the horizontal surface part where the horizontal surface part is overlapped with the coupling surface part. Therefore, welding strength between the upper rail of the seat track and the adapter bracket can be reinforced and working hours required to the welding job can be remarkably decreased compared to a conventional art where the welding was performed along an edge of the coupling surface part.

Provided is a welding connection structure for a pipe (1), in which the pipe has a double-pipe portion (2) at at least one end thereof and the double-pipe portion is formed by bending back a pipe wall (6) at the one end of the pipe inward and forming a bent-back portion in close contact with an outer pipe wall (4), and in which the pipe is connected by welding, at the double-pipe portion, to a mating member (11) to which the pipe is to be connected.

Provided is a center pillar constituting workpiece, which is equipped with a criterion excellent in the visibility of a spot-welding hitting position thereby to facilitate the welding quality management. A center pillar (3) is constituted of a center pillar outer (5) and a center pillar inner (6), which are jointed to each other by spot-welding a flange (8) formed at the center pillar inner, to the corresponding portion of the center pillar outer. The flange has its edge portion formed into a waving shape having a crest (8a) as a criterion of the hitting position for the spot-welding. The surface corrugations cannot be enlarged so much because of the thickness, but can be formed along the flange face, so that their crests (or valleys) can be enlarged. As a result, the criterion can be made so highly visible as to perform the spot welding at the precise positions according to the designs and to improve the quality of the spot welding.
摘要:
A tailored blank article and a manufacturing method thereof, which is used for partitioning an inside and an outside such as a dashboard panel for partitioning an engine room of a car body and the inside of a car room. A thick plate blank and a thin plate blank are joined by a mash-seam welding or a laser welding, and are subjected to a pressing. Thereby, the thin plate blank is bent until an inner surface of the thin plate blank is made flush or almost flush with an inner surface of the thick plate blank, subsequently, a connection part having a portion connected over a welding portion is connected to at least one of an outer surface and the inner surface of the tailored blank article comprising the thick plate blank and the thin plate blank, and then an entire tailored article including the connection part is coated. The connection of the connection part to the tailored blank article, which is performed before the coating, is performed with a portion which corresponds to a welding portion of the connection part spaced from the welding portion, to thereby form a coating film securely onto the welding portion.

An assembly of crown wheel (12) and casing (11) of a differential gear assembly (10) is adapted to welding. The casing (11) has a circular flange (17) with an axially extending lip engaged in a circular groove (33) which is further relieved at the radially outer side to give clearance for a high energy welding beam (13). The interface between crown wheel (12) and flange (17) is preferably a frusto-conical surface (70, 65) which presents an oblique angle to said welding beam.

The invention relates to a method for binding two parts (1, 8) of a vehicle seat, wherein a first part (1) is provided with at least one projection and a second part (8) is provided with at least one receiving element, whereby both parts (1, 8) are combined in the receiving element after insertion of the projection and then welded. In said method, welding of the side of the second part (8) which faces away from the first part (1) occurs within the receiving element which is embodied as a continuous bore hole.
