| Abstract Scope |
As with other fusion welding processes, electron beam welding can lead to residual stresses that limit component life and distortions that may exceed design tolerances. The use of high frequency beam deflection during welding can create “warming sources” adjacent to the weld line that may mitigate residual stresses and reduce distortion. In this study, the effect of different configurations and magnitudes of warming and cooling sources have been investigated. The number of variables makes experimental optimization difficult; hence, numerical simulation using finite element analyses has been used to explore parameter space. A focus on 2D models allows for the rapid optimization of processing parameters. The model predictions are validated against data from experimental welds on SS316 plates and the limitations of 2D simulations discussed. |
