Resistance spot welding is one of the most commonly used manufacturing methods when steel sheets are joined. It is important to see the whole process with its defects after manufacturing, before the process. The finite element solution plays a big factor in this step. In this study these defects have been accepted as the distortions after spot welding. Although they are not as big as in the beam welding processes distortions play a role in the spot welding of steels especially if they are considered as cumulative. One of the factors affecting on such distortions is the welding sequence. In this study, distortions will be obtained according to the scanning and analysing methods (Local Shrinkage Analysis) after applying several sequences and they will be compared. This research will be made on a case study which deals with an assembly group obtained from automotive sector.
