EXPERIMENTAL AND NUMERICAL ANALYSIS OF SPOT WELDED JOINTS AND CONSTRUCTIONS

M. Živkovic

Abstract

In this paper, experimental and numerical research of spot welded joints is presented. The most important mechanical properties of the base sheet are determined using specimens cut in different directions with reference to the rolling direction. Welding parameters are adopted with respect to the recommendations. The quality of the spot-welded joint is evaluated by experimental and numerical methods. The tensile test was used in choosing the most suitable spot welding regime. Several examples are analyzed. Force-displacement diagrams with fields of effective stress and strain show that implemented large strain theory gives good prediction of the joints behavior.
