مقاله جوشکاری با عنوان : A study on numerical analysis of the resistance spot welding processH. Zhigang a, I.S. Kim b,*, J.S. Son b, H.H. Kim b, J.H. Seo b, K.C. Jang c,D.K. Lee c, J.M. Kuk c چکیده:Purpose: Over the last few years, there has been a growing interest in quantitative representation of heat transferand fluid flow phenomena in weld pools in order to study relationships between the processing variables andthe quality of the weldment produced and to use this information for the optimization and mobilization of thewelding process.Design/methodology/approach: A 2D axisymmetric Finite Element Method (FEM) model has been developedto analyze the transient thermal behaviors of Resistance Spot Welding (RSW) process. In this model, thetemperature dependent material properties, phase change and convectional boundary conditions were takenaccount for the improvement of the calculated accuracy, but the determination of the contact resistance at thesurface is moderately simplified in order to reduce the calculating time through the analysis.Findings: The developed model has been employed the thermal history of the whole process (including cooling)and temperature distributions for any position in the weldment
