Numerical Simulation of Nugget Geometry and Temperature Distribution in Resistance Spot Welding
Resistance spot welding is an important manufacturing process in the automotive industry for assembling bodies. The quality and strength of the welds and, by extension, the body is mainly defined by the quality of the weld nuggets. The most effective parameters in this process are sheet material, geometry of electrodes, electrode force, current intensity, welding time and sheet thickness. The p...

متن کاملNugget Formation during Resistance Spot Welding using Finite Element Model
Resistance spot welding process comprises of electric, thermal and mechanical phenomenon, which makes this process complex and highly non-linear and thus, it becomes difficult to model it. In order to obtain good weld nugget during spot welding, hit and trial welds are usually done which is very costly. Therefore the numerical simulation research has been conducted to understand the whole proce...

متن کاملFinite Element Analysis of Temperature Distribution during Arc Welding Using Adaptive Grid Technique
Analysis of temperature and the cool ing rates during the weld ing process is essential to determine the deformation and residual stresses, and hence, the load-carrying capacity of the weldments. Numerical methods wi th nonl inear tenqperature-dependent mechanical properties with latent heat effects have been developed in recent years. The accuracy and computational efficiency of these methods ...
