Welding is globally used as the most versatile means of joining all commercial metals. In fusion welding, a weldment is locally heated by the welding heat sources. Due to the nonuniform temperature distribution during the thermal cycle, incompatible strain leads to thermal stresses, the main source of problems. Thermal stresses in the weld may lead to formation of hot cracks. Therefore, it becomes necessary to develop a model for the welding process, which would produce not only qualitative but also quantitative information on thermal stresses. In the present work, a finite element simulation of the welding process, yielding the welding induced thermal stresses in rectangular weld pool, is presented.

Finite Element Analysis of Weld Thermal Cycles Using ANSYS aims at educating a young researcher on the transient analysis of welding thermal cycles using ANSYS. It essentially deals with the methods of calculation of the arc heat in a welded component when the analysis is simplified into either a cross sectional analysis or an in-plane analysis. The book covers five different cases involving different welding processes, component geometry, size of the element and dissimilar material properties. A detailed step by step calculation is presented followed by APDL program listing and output charts from ANSYS. Features: Provides useful background information on welding processes, thermal cycles and finite element method Presents calculation procedure for determining the arc heat input in a cross sectional analysis and an in-plane analysis Enables visualization of the arc heat in a FEM model for various positions of the arc Discusses analysis of advanced cases like dissimilar welding and circumferential welding Includes step by step procedure for running the analysis with typical input APDL program listing and output charts from ANSYS.
