A novel technique of implementing a well-designed simulated welding is proposed to precisely locate the soft zone. Essential factors such as hardness profiles, geometrical dimension, microstructures, and elemental distributions enable fair comparison of key heat-affected zone sub-regions between actual and simulated welding samples. The expansion of the heat-affected zone width by approximately 3 times facilitates the identification of the elusive soft zone.
A novel technique, by implementing a well-designed simulated welding, is proposed to precisely locate the soft zone. We capture and demonstrate that essential factors, including hardness profiles, geometrical dimension, microstructures, and elemental distributions, could enable fair comparison of key heat-affected zone sub-regions between actual and simulated welding samples. It is found that the width of the heat-affected zone has been expanded approximately 3 times, which will unambiguously facilitate the identification of the elusive soft zone.
