Abstract: A method to join three panels together for a motor vehicle includes one or more of the following: layering the three panels, the three panels including a first panel, a second panel, and a third panel, the second panel being positioned between the first panel and the third panel, the third panel having a higher electrical conductivity than the first panel and the second panel; joining the first panel and the second panel together; and joining the third panel to the first panel and the second panel.

Abstract: A method of forming a vehicle body structure includes pre-welding a patch blank to a base blank with a series of resistance spot welds to form a pre-welded blank assembly. After pre-welding, the pre-welded blank assembly is deformed into the vehicle body structure. The deformation of the pre-welded blank assembly is carried out by a suitable metalworking process, such as stamping, and results in concurrent deformation of the base blank and the patch blank. Following deformation of the pre-welded blank assembly, additional weld joints may optionally be formed between the base blank and the patch blank, wherever desired, to better secure the blanks together.

Abstract translation: 一种形成车体结构的方法包括用一系列电阻点焊将预焊接到坯料上以形成预焊焊接组件。 在预焊之后，预焊毛坯组件变形成车体结构。 预焊毛坯组件的变形通过合适的金属加工方法进行，例如冲压，并导致基坯和补片坯料同时变形。 在预焊接坯料组件变形之后，可以任意地在基板坯和补片坯料之间形成额外的焊接接头，以便更好地将坯料固定在一起。
