In most cases, the steel shell construction method predominates in today's body structures. In order to continue to meet the higher customer expectations with regard to product diversity, environmental awareness and safety requirements, it is necessary to develop alternative vehicle concepts. One possible trend is heading towards section-intensive construction methods and space frame concepts. Advantages result from the decrease in the consumption-relevant vehicle weight, from an improved crash behaviour and from a lower number of parts. This permits the more flexible and more cost-favourable organisation of the fabrication. While resistance spot welding in lap joints is often used in the shell construction method, the space frame construction method necessitates welding procedures which can produce various joint geometries such as T-joints and butt joints with sufficiently large weld cross-sections. The higher heat input leads to increased shrinkages and deformations during and after the welding process. In highly automated bodymaking, there is a considerable need for detailed knowledge about the welding-induced distortion and about the effectiveness of distortion-reducing measures. The type and amounts of the distortions can already be predicted during the design phase. Particular interest is attached to information about the time-related sequence of the welding distortion.
