Correction: Tamadon et al. Flow-Based Anatomy of Bobbin Friction-Stirred Weld; AA6082-T6 Aluminium Plate and Analogue Plasticine Model. Appl. Mech. 2020, 1, 3–19

In the original publication [1], there were mistakes in the captions of Figures 4 and 12. Figure 4a in this published paper [1] in Applied Mechanics is an adaptation of Figure 6b in authors’ previous publication [2] in Metals, representing plasticine analogue sample produced in (75 rpm, 50 mm/min). The underlying image has been adapted in different ways for the two papers. To show the correct process parameters, the corrected caption of Figure 4 appears below:

Figure 4. Macroscopic structural features of bobbin friction stir welding, (a) plasticine slab (75 rpm, 50 mm/min), and (b) AA6082-T6 aluminium plate (650 rpm, 400 mm/min). In both cases, the rotation is clockwise when viewed from above, although, this view is from below. Figure shows the common features. Image adapted from Tamadon et al., Metals; published by MDPI, 2018 [14].

Figure 12 in this published paper [1] in Applied Mechanics is an adaptation of Figure 2 in authors’ previous publication [3] in Metals. The underlying image has been adapted in different ways for the two papers. However, an error existed in the Applied Mechanics paper [1] regarding the welding process parameters (rpm and feed rate). The corrected caption of Figure 12 appears below:

Figure 12. The proposed flow patterns at the AS location of the stirring zone, drawn at the weld cross-section; (a) in presence of the tunnel void (w = 400 rpm, 350 mm/min), and (b) for a defect-free sample (w = 650 rpm, 400 mm/min). Image adapted from Tamadon et al., Metals; published by MDPI, 2019 [1].

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
