Resistance Spot Welding Bonding (RSWB) is a hybrid joint method that includes the chemical force-based process of bonding and the physical force-based process of welding. When correctly executed, several advantages over traditional methods are found in fatigue performance, tensile strength, energy absorption, stiffness, and corrosion resistance. This study relates the spreading behavior of epoxy adhesives between Advanced High Strength Steels (AHSS) sheets during the weld-bonding process. To predict the presence of the adhesives within the nugget fluid dynamics models, the static contact, and dynamic resistance were used. Computational Fluid Dynamics (CFD) was performed to estimate the consequences using different cap shapes, and adhesive thickness in the remnant adhesive in RSWB. Verification and validation were performed against high-speed camera, SEM, and EDS measurements. Results showed that the fluid dynamic models, static contact and dynamic resistances between the sheets are good tools to predict remnant adhesive on RSWB. |
