Problems solved by technology

Sheet metal thickness ratios and differences in the resistance values ​​of the materials used often do not allow high-quality welding by resistance spot welding at all, for which it is often necessary to resort to laser welding which is substantially more difficult and more expensive in terms of equipment
Furthermore, in panel welding, especially for hot-rolled steel used in bodywork construction, localized material defects occur in the weld metal zone and / or in the heat-affected zone of the weld
This can have a negative impact on material properties, e.g. in the event of an accident, sudden rupture due to tearing at extreme forces

Embodiment Construction

[0068] Figures 1 to 8 Various views, partial sections and details of a body part 2 , which is embodied here as a B-pillar 1 , are shown. 3, 4, 5, and 7, it can be seen that the vehicle body component 2 comprises an outer panel 3, an inner panel 4 and a reinforcement panel 5 arranged between the outer panel 3 and the inner panel 4, the panel 3 5 through the respective flanges 6 to 8 are connected sideways in contact with each other, that is, through the outer panel flange 6 of the outer panel 3, the inner panel flange 8 of the inner panel 4, and the reinforcing flange 7 of the reinforcing panel 5, wherein For example the outer panel flange 6 surrounds at least the reinforcement flange 7 to form a positive interlock.

[0069] Figure 3a and 3b clarifies the enclosing, and especially the hemming, process in a two-step approach, Figure 3a and 3b each is based on figure 2 A partial sectional view of the cross-sectional profile A-A, Figure 3a The outer panel flange 6 is s...

Abstract

The invention relates to a body member (2) of a vehicle body having an outer sheet (3) and a reinforced sheet (5), in particular a B-pillar, wherein the edge-sides of the outer sheet (3) and the reinforced sheet (5) are connected with one another over corresponding flanges(6,7). The outer sheet flange (6) wraps around the flange of the reinforced sheet especially by side pressing, so as to form a positive interlock at least in some sectors.

Description

technical field [0001] The invention relates to a bodywork component of a vehicle, in particular a B-pillar. Background technique [0002] In the thermal joining methods of vehicle body structures, for example resistance spot welding is commonly used, often in combination with adhesive bonding methods or laser welding, when assembling the flanges of the panels. However, to strengthen components such as the A- and B-pillars, high-strength and ultra-high-strength steels, sometimes with large sheet thicknesses, are increasingly being used, which makes it difficult to attach to the rather thin outer walls. A similar degree of difficulty is encountered in the welding of mixed structures, for example, in the welding of steel / light alloy structures. The sheet metal thickness ratios and the differences in the resistance values ​​of the materials used often do not allow high-quality welding by resistance spot welding at all, for which it is frequently necessary to resort to laser we...
