Abstract
In this study, the effects of electrode surface design on the resistance spot weldability and degradation of the electrode following resistance spot welding (RSW) of aluminum 6014-T4 alloy were investigated. A new patterning method that can be produced through repetitive pressurization was applied to the electrode, producing a lattice-like pattern..... More

DOI: https://doi.org/10.3365/KJMM.2019.57.11.715

Abstract
Evaluation of electrode degradation in resistance spot welding of 1180TRIP steel was carried out through an electrode life test, and weldability testing was performed by the measurement of the nugget size, the peak load analysis and the measurement of the electrode tip size at 30 intervals. Analysis of the change..... More
