Figure 11 Temperature distributions [°C] during: A, I pass at timet = 66.67 s and B, II pass at time t = 315 s.
Figure 12 compares the experimental and the predicted FZ and HAZ. As shown in this figure, the geometry and shape of both weld seam and HAZ are well numerically replicated. As matter of the fact, the HAZ can be defined as the section reaching a temperature higher than 727 °C during the welding process.54
