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] Figure 1 to 8 Different views, partial cross-sectional views and detailed views of the vehicle body component 2 are shown, and the vehicle body component 2 is implemented as a B-pillar 1 here. In particular, it can be seen from the partial cross-sectional views according to FIGS. 3, 4, 5, and 7, that the vehicle body member 2 includes 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 To 5 are connected in contact with each other through the respective flanges 6 to 8 side, that is, through the outer plate flange 6 of the outer plate 3, the inner plate flange 8 of the inner plate 4, and the reinforcing flange 7 of the reinforcing plate 5, wherein, For example, the outer plate flange 6 at least encloses the reinforcing flange 7 to form a positive interlock.

Abstract

The invention relates to a bodywork component (2), in particular a B-pillar (1), having an outer panel (3) and a reinforcement panel (5), the sides of which are passed through corresponding The flanges (6,7) are connected together in contact. The outer panel flange (6), in particular by crimping, surrounds the stiffener flange (7) to form a positive interlock at least in some parts.

Description

Technical field [0001] The invention relates to a vehicle body component, especially a B-pillar. Background technique [0002] In the thermal joining method of the vehicle body structure, when assembling the flange of the panel, for example, resistance spot welding is usually used, and an adhesive method or laser welding is often combined. However, in order to reinforce components such as A-pillars and B-pillars, high-strength and ultra-high-strength steels that sometimes have a large metal plate thickness are increasingly used, which makes it difficult to connect to relatively thin outer walls. A similar degree of difficulty is encountered in the welding of hybrid structures, for example, in the welding of steel / light alloy structures. The thickness ratio of the metal plates and the difference in the resistance value of the materials used often do not allow high-quality welding by resistance spot welding at all. For this reason, it is necessary to frequently resort to laser wel...
