Estimation of Mechanical Properties of Welded Joints Produced by Resistance Spot Welding with Electromagnetic Stirring

The paper reveals investigation results of effect of external electromagnetic fields on mechanical properties of welded joints produced by resistance spot welding. Results of research of external electromagnetic fields effect on the mechanical properties of constructive and stainless steels and joints made from different materials were presented. Samples which are suitable for performing static-load tests of spot welding for the minimization of data misrepresentation were proposed and the analysis was performed.
