Abstract: The Arplas welding process is widely used in the automotive manufacturing field, particularly for exterior parts such as body panels and side frames, owing to its advantages of low welding energy, small heat-affected zone, and minimal mechanical deformation. However, due to the specificity of this process, welding quality is susceptible to influences from embossing, electrodes, sheet lapping, etc., making the process stability difficult to control. Therefore, based on the Bosch 7000 servo welding system and medium-frequency direct current welding gun, this paper establishes the embossment standard through boss height tracking experiments, and investigates the relationship between parameters and spattering using orthogonal experiments to determine the optimal parameter range for qualified quality. Additionally, the effects of electrode life and embossing process on welding quality and spattering are studied. A micro high-precision electrode dressing technology is proposed, which, combined with electrode detection and wear compensation, significantly improved the stability of the welding process, reduced spattering, effectively extended electrode life, and enhanced Arplas welding stability. The micro high-precision electrode dressing and boss cleaning technologies are of significant guiding importance for the optimization of the Arplas welding process.
