Effect of Heat Input on Porosity Defects in a Fiber Laser Welded Socket-Joint Made of Powder Metallurgy Molybdenum Alloy
Round 1
Reviewer 1 Report
This manuscript presents the results of welding process and studied the welding defects of molybdenum alloy. Study is interesting and I wish it to be published after minor modifications, which should help to improve clearly and quality of presentation.
1) English, especially, in the Abstract and Introduction, should be corrected. For example, multiple verb tense is required in line 3, line 16, and line 21, etc. I recommend one of the professional English editing services.
2) Line 52. What is meaning of An’s study [25]? The first author of the reference [25 ] is Geng. It is better writing Gend [25] found/observed/explained etc… Be sure that the order of Reference list is right.
3) Line 56 “A generally accepted wisdom” seems unscientific.
4) Line 67. Point was missed.
5) Weld junctions are sown, but heat-affected zones did not show in Figure 5 (for example). Please, show heat-affected zones and there structure.
6) Line 120-121.Will measure the junction areas.
7) Explain the microcavities influence to the final defects parameters.
8) Explain , what was a reason of the different shape of the porous in two welding modes.
9) What are the black elongated defects in the near junction areas in Figure 13. Please, clarify.
10) Figure presentations should be improve. Please, make script larger, script color in Fig.7 make white. Clarifications need for Figure 12 and figure 13.
11) Figures captures are not clear; meaning of a, b, etc. should be explained in the captures.
