Round 1
Reviewer 1 Report
The study is novel and interesting. Although, a few things need to be taken care of.
- The writing needs a little improvement, especially the grammar and flow.
- Line 86 is incomplete. Kindly check.
- Ci has been interpreted as speed of water. Please correct this.
- Section 2.1 needs more elaboration. Discuss in detail the working principle behind the technique.
- Figure 2 needs to be more explanatory. It is not clear. Provide more geometrical details and FE details. Kindly mention the software used for the simulation along with the version and release.
- What was the element type used? Mention the material models. Explain how the plane wave was applied.
- Kindly elaborate on line 117-118.
- Section 2.2 was about determining the critical angle of ultrasonic transducer to generate Rayleigh waves on the piston rods. Did the author perform multiple simulations? If yes, then how many and what were the varying parameters? Kindly elaborate more on the critical angle parameter and its importance.
- Line 111 to 114 is not clear. Kindly explain.
- The study has presented a good quality based assessment of the defect signals but can the author establish an assessment system to quantify the defects from the analysis of the defect signals?
- Discuss more on the relative positioning of the transducers and their effects on the quality of received defect signals.
- Why was water chosen instead of air as the medium? Are they any other fluids that can replace water?
- The authors have mentioned that the incident angle would be different for different materials. Which grade of steel was the piston made of? Will the angle of incidence vary between different grades too?

Reviewer 2 Report
What is the minimum detectable size?
Does the author have a case study of actual defect detection, because the actual defects are not exactly as described in the text?
The legend for Figure 14 should be placed below the picture
