Numerical Analysis of the Effect of Electrode Strips on Spot-Welding Process

Abstract:

Resistance spot welding is an important technology widely used in manufacturing industry. It is a coupling process which involves thermal, electrical and mechanical physics fields. Due to the formation of weld nugget is transient and non-visible, the experimental analysis is difficult. In this paper, a thermal electrical-mechanical coupling technique is carried out by finite element method to study the effect of electrode strips on weld nugget formation and surface indentation under different processing parameters. Experimental and numerical analysis results show that the electrode strips can reduce the surface indentation depth effectively and is helpful to the formation of weld nugget.
