| description | In this study, gas tungsten arc welding of ferritic stainless steel and grain
size distribution in heat affected zone of the welded samples were
investigated. Both similar and dissimilar arc welding operations were
considered where in dissimilar welding joining of stainless steel to mild
steel was examined. In the first stage, a three-dimensional model was
developed to evaluate temperature field during and after arc welding while
the model was performed using finite element software, ANSYS. Then, the
effects of welding heat input and dissimilarity of the joint on the weld pool
shape and grain growth in HAZ of stainless steel was investigated by means of
model predictions and experimental observations. The results show that the
similar joint produces wider HAZ and considerably larger grain size structure
while in the dissimilar welds, the low carbon part acts as an effective heat
sink and prevents the grain growth in the stainless steel side as well
reduces the welding maximum temperature. |
