Laser Butt Welding of Thin Ti6Al4V Sheets: Effects of Welding Parameters
Round 1
Reviewer 1 Report
- How many times were each experimental condition performed in Table 2?
- Defocusing distance is a very important parameter in laser welding. Why was the experiment performed only when the defocusing distance was 5mm?
- Explain what L11 ~ L19 mean in Figure 4. Ex) L11 : 2.6kW, 2.6m/min
- In Figures 5 and 6, each point must be marked as L11~L19 for comparison. In Figure 5, for 2.8 kW, it looks like there is only one elongation. In Figure 6, at 2.6m/min, only 2 elongations are visible, and at 2.8m/min, only 2 tensile strengths are visible. If shapes are overlapped, it is recommended to draw only lines rather than filling the inside of the shape with color.
- Why did you explain only one case of 2.8kw and 3m/min in 3.4 Fracture Surface Analysis section? There are no analyzes for the remaining 8 cases.

Reviewer 2 Report
- I think, abbreviations “Nd” and “YAG” could be explained (page 1, line 43).
- Probably, trend lines should be added on Figure 5 for better visualization and interpretation of the results. Same is for Figure 6.
- Page 6, line 142. Did the sample fail itself? Or in the result of the application of some load?
- You investigated several regimes of welding. Which one is more preferrable and on which criteria this preference could be based? Please, if possible, give it, briefly, in the conclusion.

Round 2
Reviewer 1 Report
- Add response of S/N 1 (Two sheets measuring 100 × 60 × 1 mm each were joined. Two tensile samples ~) in Section 2 Materials and Methods.
- Modify the welding speed, which is the X-axis range in Figure. 6 (2.5 m/min ~ 3.1 m/min)
