Development of Resistant Spot Welding Technology for Automotive Ferrite-Martensitic Dual-Phase Steels with Joint Application of Finite Element Modelling and Experimental Research

Abstract:

In this paper spot-welding technology of sheets made of Dual-Phase (DP) steel, which is one of the most important materials in the automotive industry, has been analyzed using finite element modelling and experimental research. The traditional, continuous energy input and the symmetric double pulse as non-continuous energy input were compared for resistance spot welding focusing on the advantages of pulsed energy input. For numerical analysis an axisymmetric coupled finite element model was developed to study the effect of welding time and current intensity on nugget size and thermal history in resistance spot welding process using MSC.Marc software package. The cross-section macrostructures of the welded specimens were examined and compared to the predicted size of the weld nugget and heat affected zone.
