A Smart Handheld Welding Torch Device for Manual Spot Laser Welding
Round 1
Reviewer 1 Report
The present work is devoted to the study of a innovative device for laser spot welding of stainless steel. The work is interesting but some major revision are required before publication.
-The introduction section should be revised considering for example for related to laser welding of DSS (I can suggest https://doi.org/10.3390/met8121074)
-Please add at the end of the introduction the novelty of the work
-The main lack of the paper is the absence of proper characterization of the weldings. What is the microstructure? And the hardness? Please perform proper analysis to characterize the obtained spot weldings because stereo microscope images are not enough
-Please add a brief conclusion section written as bullet points

The present work is devoted to the study of a innovative device for laser spot welding of stainless steel. The work is interesting but some major revision are required before publication.
Thank you for your valuable comments and contribution to the development of our article. You can find our explanations about the changes we made in our article in line with your suggestions and comments below.
Point 1: The introduction section should be revised considering for example for related to laser welding of DSS (I can suggest https://doi.org/10.3390/met8121074)
Response 1: It has been revised considering the proposed article. Please see page 3.
Point 2: Please add at the end of the introduction the novelty of the work.
Response 2: The novelty of the work has been added at the end of the introduction. Please see page 4.
Point 3: The main lack of the paper is the absence of proper characterization of the weldings. What is the microstructure? And the hardness? Please perform proper analysis to characterize the obtained spot weldings because stereo microscope images are not enough.
Response 3: In line with your comments, microscope images of the microstructure (obtained by vertically cutting from the welding point of the 2 mm thick stainless sheet material) and explanations about the subject have been added to the article. Please see the new Figure 4 and the explanations on pages 6-7.
Point 4: Please add a brief conclusion section written as bullet points.
Response 4: A short conclusion, written as bullet points, has been added to the article. Please see 12.

Reviewer 2 Report
The manuscript entitled “applsci-1984686” dealing with laser welding has been reviewed. The paper has been nicely written but needs significant improvement. Please follow my comments.
- Add some quantitative results to the abstract.
- Figure 1 is not clear. Please add more detail to this figure. Figure 1(a) needs to be justified.
- How did you select the material properties in table 1? Provide a reference.?
- The wording in Figure 3 is not readable.
- Add more detail to Section 3.2 “Design, programming, and welding with the”.
- Laser welding is used in additive manufacturing which has many advantages over the conventional manufacturing method. Please read the following article and add to the introduction to show the experimental application of additive manufacturing and the advantage of this process over conventional manufacturing. “The effect of absorption ratio on meltpool features in laser-based powder bed fusion of IN718”
- Please update the introduction with the new publications on the application of lasers in emerging manufacturing processes (additive manufacturing) and compare your work with these publications.
· Multiple recycling of nickel alloy powder for selective laser melting process: influence on properties of the powder and printed material
· Modeling residual thermal stresses in layer-by-layer formation of direct metal laser sintering process for different scanning patterns for 316L stainless steel
· The influence of laser power and scanning speed on the microstructure and surface morphology of Cu2O parts in SLM
