Remote Fibre Laser Welding of Advanced High Strength Martensitic Steel

Round 1

Reviewer 1 Report

The manuscript entitled ‘Remote fibre laser welding of advanced high strength martensite steel’ falls within the scope of the journal Metals. The paper contains very interesting experimental results. It is of sufficient scientific interest and has originality in its technical content to merit publication. The authors have cited the relevant literature, although some interesting items have been omitted. Methods, interpretations of results and conclusions are correct and novel. The issues were well presented. In terms of content, the analysis does not raise any objections. The arrangement of work maintains substantive continuity and constitutes a logical whole. However, the manuscript is not suitable for publication in its present form.

The manuscript requires small corrections in the literature review. In my opinion, the following papers should be included:
