Influence of the welding process on martensitic high strength steel
Journal Title: Production Engineering Archives - Year 2014, Vol 0, Issue 2
Abstract
The subject of the study is martensitic 22MnB5 steels, which are used in the automotive industry. The main purpose of the per-formed analyses is a study of strength differences in heat affected zones of the spot welding. For the needs of the strength decrease assess-ment, the critical layer of the heat affected area was experimentally simulated. The aim of the work is to determine the most suitable method-ology for evaluating the local changes of the elastic-plastic material response. The aim of this work is to determine the optimal methods for the determination of the yield strength and to find a firming trend in these zones.
