Response
An explanation of the change in hardness after the burnishing process is presented in the manuscript.
The basic features of metals and their alloys include surface hardness and microhardness, which are directly related to the properties of the surface layer, such as: resistance to frictional wear, fatigue strength, residual stresses and plasticity. The surface hardness depends on the type of material and the strengthening, thermal or thermo-chemical treatment carried out. The change in hardness and microhardness in the burnishing process is influenced by the burnishing tool, which, under the action of force, causes local elastic and plastic deformations in the contact zone with the workpiece. The phenomenon of strengthening mainly occurs in the surface layer. The grains are fragmented, flattened and elongated in the direction of the greatest deformations, creating a crushed texture. The ability of a material to be strain hardened depends largely on its structure and the value of burnishing parameters. The burnishing process is limited due to the permissible degree of plastic deformation and exceeding it results in technological cracking and flaking of the processed surface.
- The vast majority of cited references are older than five to ten years. This reduces the relevance of the work. It is advisable to include more references in publications less than five years old.

Response
Thank you very much for the valuable tips that we received in the review for publication. The literature review showed that issues related to burnishing of welded joints of EN AW-6060 aluminum alloys are not available in journal databases. Therefore, in the publication "The influence of the Burnishing Process on the Change of Surface Hardness, Selected Surface Roughness Parameters and the Material Ratio of the Welded Joint of Aluminum Tubes" the authors presented research that shows an improvement in the quality of the machined surface while strengthening the surface layer of the welded joint and native material. The authors fully agree with the reviewer's comments, which indicates that additional test results should be performed and presented to fully determine the impact of burnishing treatment on the joint and the native material. However, at the current stage of research, its impact on selected parameters of surface roughness, material fraction and surface hardness was determined. In the future, research is planned on the optimization of burnishing parameters, taking into account the quality of the machined surface and the strengthening of the surface layer, using the SRMD rolling burnisher from Yamato and then the hydrostatic burnisher from ECOROLL. Next, the research team plans to perform the tests indicated by the reviewer. In addition, corrosion resistance and contact fatigue tests will also be performed.
Reviewer 3 Report
Comments and Suggestions for AuthorsThe influence of the Burnishing Process on the Change of Surface Hardness, Selected Surface Roughness Parameters and the Material Ratio of the Welded Joint of Aluminum Tubes.
Very good manuscript.
Authors need to specify which type or article they are aiming to work here.
Rows 38 and 40, can you work on the subscripts?
Please consider taking out Figure 1. We all know what is a lathe, the figure 2 makes sense since you have the sample mounted in the lathe and that is the way you are going to work with the item...
Can you merge or couple Figures 3 and 4 in one single image? probably side by side...
Figure 5b, what is the scale you used here?
In your conclusions, you mentioned that further research must be done. What is the value added of this work then? compared to other published research on aluminum alloys...
I highly recommend the authors to search and identify more recent references, please use or work on those which are > 2021.
Comments on the Quality of English Language
English grammar needs minor work. Parragraphs reading flow could be improved with a review on grammar.

Comments and Suggestions for Authors
- Authors need to specify which type or article they are aiming to work here.
Response:
The authors wrote a scientific article based on their research
- Rows 38 and 40, can you work on the subscripts?
Response:
The authors have made corrections in the manuscript
The publication has changed subscripts for marking materials, cutting parameters, surface roughness parameters, material ratio and index of relative surface strengthening.
- Please consider taking out Figure 1. We all know what is a lathe, the figure 2 makes sense since you have the sample mounted in the lathe and that is the way you are going to work with the item...
Response:
Of course, the authors agree with the opinion that lathes are commonly known machining machines. There are many manufacturers available on the market who offer many types . The publication presents a view of the cutting machine in order to provide full information about the research methodology, because currently CNC machine tools are often used in industry and scientific institutes. In this case, the process was carried out on an older generation conventional lathe.
- Can you merge or couple Figures 3 and 4 in one single image? probably side by side...

- Figure 5b, what is the scale you used here?
Response:
In the publication, the authors presented the view of the impression from the hardness measurement carried out on the Qness 250M hardness tester with the HV10 load. The imprint is measured in [μm] and its diagonals are: diagonal 1 = 408.20 µm, diagonal 2 = 396.51 µm.
- In your conclusions, you mentioned that further research must be done. What is the value added of this work then? compared to other published research on aluminum alloys...
Response:
A review of the literature revealed few publications related to the burnishing process of welded joints of aluminum alloys. Moreover, soft materials pose problems during the burnishing process. In the publication, the authors presented research results that demonstrate an improvement in the quality of the machined surface while strengthening the surface layer of the welded joint and the native material.
The added value of the publication is that after welding, the EN AW-6060 aluminum alloy can be subjected to a burnishing process. The tests used burnishing parameters selected on the basis of experience and knowledge of the burnishing process with a Yamato SRMD burnishing tool. Further research will include the optimization of burnishing parameters in terms of the surface roughness reduction rate and the degree of surface strengthening. After determining the potential surface properties, tests of functional properties are planned using optimal burnishing parameters. Additionally, tests are planned using a hydrostatic burnisher from ECOROLL
