Analytical Solutions for Moving Elliptical Paraboloid Heat Source in Semi-Infinite Plate

Article Preview

Abstract:

An attempt has been made in this paper to findout the trainsent temperature distribution on the welded plates through analytical as well as numerical method considering double elliptic paraboloid moving heat source volume.It has been assumed that heat is distributed through gaussian manner on the welded plates and modes of heat transfer for welded plates are conduction as well as convection.With the help of these solutions dimnesions of weld bead geometry,HAZ width and thermal stress have been predicted and validated with the experimental data.
