Simplified Methodology Research for Parameter Setting of Resistance Spot Welding

Abstract

The research is explored an efficient methodology in parameter setting for RSW (resistance spot welding). The methodology mainly focusses on weld cycles and weld current, which has included a process for parameter selection, performance evaluation, and failure mode analysis. Effects on welding resistance caused by various technical parameters. Relationship between weld cycles, weld current and the mechanical performance will be established by simplified model. Also, the parameter setting of welding operation, inspection methods, failure modes and control system will be discussed in the following content. This methodology will lead to higher efficiency and optimized quality during for manufacture parameter determination in sample A round before massive production. A proper resistance spot welding will be more economical engineering method for joints in the industry.
