Influence of welding current shape on expulsion and weld strength of resistance spot welds

Pages 250-254 | Published online: 04 Dec 2013
 

Abstract

The present paper presents the influence of welding current shape on weld strength of resistance spot welds of zinc coated mild steel sheets. The influence is analysed at different levels of the electrode wear. Welding currents with different peak values and different RMS (root mean square) values were used in the experiment. The results show that welding current with high peak values implies higher weld strength.
