摘要： A method of single sided spot welding includes the steps of providing a metal tube having a convex surface portion and providing a metal sheet for welding to the metal tube. The method also includes the steps of contacting the metal sheet with the convex surface portion of the metal tube and contacting the metal sheet with a welding electrode. The method further includes the steps of supplying power to the welding electrode for melting metal and solidifying the molten metal to form a weld nugget between the metal sheet and the metal tube.

摘要： The present invention is for a method of lap joining two tubular members and then hydroforming the tubular assembly. An insert end of the first tubular member is inserted into a receiver end of the second tubular member to form a lap joint. A filler metal ring is placed about the outer periphery of the insert end so that it is adjacent the opening of the receiver end of the second tubular member. Heat is applied to braze or solder the lap joint, forming a tubular assembly. The tubular assembly is then hydroformed during which time a supplementary mechanical lock may be formed in the lap joint.

摘要： A method for hydroforming a tubular structural member of generally polygonal, flat walled cross section in which the various walls in the final part do not have the same thickness. A cylindrical tubular blank is extruded in which the outer surface is round, but in which the inner surface is asymmetrical, providing several contiguous angular sectors or portions of varying width and thickness. Each individual angular portion is tailored as to thickness and width to correspond to a respective wall in the final part. The blank is oriented between in a die cavity so as to align each angular portion with a respective wall of the finished part, and hydroformed in conventional fashion.

摘要： A method of progressive hydro-forming of a tubular member includes the steps of positioning a tubular member between open die halves mating with one another to define a first tubular cavity portion in a first stage. The method also includes the steps of progressively closing the die halves and applying hydraulic pressure to expand and conform the tubular member to the first tubular cavity portion in the first stage. The method includes the steps of positioning the expanded tubular member in a second tubular cavity portion in a second stage and progressively closing the die halves to progressively deform the expanded tubular member within the second tubular cavity portion. The method includes the steps of applying hydraulic pressure to expand and conform the expanded tubular member to the second tubular cavity portion in the second stage.

摘要： A method of forming a vehicle body side structure assembly includes the steps of providing a plurality of tubular members to form a frame structure and assembling the tubular members together to pre-form the frame structure. The method also includes the step of positioning the pre-formed frame structure between open die halves mating with one another to define a tubular cavity portion. The method includes the step of closing the die halves to capture the pre-formed frame structure within the tubular cavity portion. The method further includes the step of pressurizing an interior of the pre-formed frame structure to expand and conform the pre-formed frame structure to the tubular cavity portion to form a final frame structure.

摘要： A vehicle space frame is built up piece by piece into an initial or rough frame, consisting of standard, cylindrical metal tubes welded to matching cylindrical plugs of hollow, nodal joints. All weld seams are circular and, therefore, easily and quickly formed, and the initial frame need be formed only with the accuracy that plugging the ends of the tubes into the joints will achieve. The entire interior of the initial frame is then clamped between a large pair of dies with mating cavities, and hydroformed to provide a final frame with the desired non cylindrical cross section and accurate, final shape and form.
