Abstract

Weld pool simulation plays a significant role in thermal stress analysis, residual stress calculation as well as microstructure modeling of welded joints and structures. This paper aims to describe the analytical solution for a new hybrid double-ellipsoidal power density moving heat source in semi-infinite body & its application in weld pool simulation. The solution has been obtained by superimposing the solutions for various parts of the proposed hybrid double- ellipsoidal heat source. The weld pool geometry subjected to various heat source parameters has been calculated and compared with results p
