Figure

Table 1 gives the process parameter values. The last parameter corresponds to the starting method
Fig. 3. Simulated geometry and mesh descriptions.
Fig. 4 presents the melt pool shapes, the thermal fi eld and ve- ve-locity fi eld vector at different times
Fig. 7 shows a comparison between the measured and the simulated fusion zones. In order to have a transient validation, the shapes are compared at t ¼ 9 s and t ¼ 20 s
