Abstract
In this paper, significant aspects of weld process double ellipsoidal moving heat source geometric parameters are investigated. A three-dimensional finite element analysis is performed for AISI 304 stainless steel thin cylindrical components. During simulations, a sequentially coupled thermo-metallurgical-mechanical analysis is employed for sixteen different geometrical conditions of heat source model. The results reveal that there is a marginal affect on weld pool size and shapes, temperature distributions with the variation in moving heat source geometric parameters; whereas no influence on the residual stress distributions. Moreover, the validity of the numerical simulation results is validated through full-scale shop floor welding experiments.
