It is well known that welding thermal stresses and resulting residual stresses influence the strength of welded construction, causing troubles such as brittle fracture, buckling and weld cracking. At the instant of welding, a limited portion of the welded joint is heated up to a very high temperature and cooled down to room temperature. In the thermal cycle which takes place, the temperature distribution changes with time and the plastic deformation develops. They affect the mechanical properties of the material. In order to perform a reliable theoretical analysis, the above mentioned factors should be taken into account. The authors extended their developed theory of thermal elastic-plastic analysis with consideration of the effects of changes (that is, temperature-dependence and plastic history-dependence) of the material properties, introducing a combined model of isotropic and kinematic rules as the workhardening rule.
