Fig. 9. Total displacements predicted by the model. The undeformed shape is highlighted in light green.

The comparison of out of plane deformation between numerical and experimental analysis is shown in Fig. 10. The errors corresponding to the two wings were found to be equal to 0.09 mm and 0.13 mm, respectively. The direction of deformation was predicted correctly.

Fig. 10. Comparison of experimental deformation (red arrow) with numerical prediction (yellow arrow).

It should be noted that on the side where the value of the wing deformation was found to be 0.19 mm, three more runs were deposited. Probably, even the numerical deformation would have been different if the actual welding run sequence was included. This level of detail is however against the spirit of the proposed simplified methods.
