Study on Finite Element Analysis of Resistance Spot Welding to Study Nugget Formation

Abstract

Resistance Spot Welding is being used inside the enterprise for sheet becoming a member of system in particular within the automobile and aerospace industry. The complicated behavior of this system must be analyzed to set the choicest parameters to get the choicest weld great. This paper affords the FEA simulation of the RSW procedure. It requires modelling of complex interactions among electrical, thermal, metallurgical and mechanical phenomena. A 2d axis symmetric FEM model has been evolved to examine the temporary thermal behaviors of technique the usage of ANSYS software and matched structural ­ thermoelectric evaluation is done by means of the usage of superior coupled field detail PLANE223 to simulate the thermal characteristics of RSW technique. The targets of this evaluation is to understand physics of the system and to expand a predictive device lowering the range of experiments for the optimization of welding parameters.
