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.
