Qualitative and quantitative analysis of misaligned electrode degradation when welding galvannealed steel

Xing, Bobin; Yan, Shaohua; Zhou, Haiyang; Chen, Hua; Qin, Qing Hua

Description

Electrode misalignment, induced from the flexibility of welding machine gun of spot welder or the potential poor fit-up, leads to the high tendency of expulsion and asymmetric nugget shape. Yet very few studies have focused on the influence of misalignment on the electrode degradation and microstructure evolution of the electrode, especially when welding galvannealed steel. This paper investigates the degradation of such misaligned electrodes when spot welding galvannealed steel. To reveal its...[Show more]
