Abstract

It is possible to reduce residual stresses of welding by the low temperature stress relieving. The technique is not applied in any field today because the optimum conditions are hard to define for every weldment. In this regard, the authors have already reported that the technique can be simulated by the finite element method based on thermo-elasto-plastic theory.
In this paper, the calculated results of the technique for patch welding of disc are reported and the optimum conditions are shown in discussions. The conditions can be defined using the calculated results here, but it is shown that they are affected by boundary conditions. As a conclusion, the optimum conditions of the technique can be analized by the theory, but the examinations of the conditions are necessary for better treatments.
