“…Imperfections, according to [ 37 ] are irregularities or deviations from the specified shape or location of cut. As a result of hydrodynamic flow of molten material, gas flow fluctuation and oscillation of the laser head, a characteristic drag line pattern forms on laser-cut surfaces [ 38 , 39 ]. The drag lines have different heights and are spaced at different distances, which means that different areas of the surface of the cut part will have a different quality and shape.…”

“…The characteristic striae appear on the cut surface, which indicates that the material escapes from the cutting kerf [9,3]. Their presence is caused by oscillation of the laser head, laser power fluctuation, gas flow fluctuation and hydrodynamic flow of molten metal [6].…”

“…The heat coming from the molten metal penetrates to cold areas surrounding the cutting kerf, which causes structural alternations close to the cutting kerf. This, in turn, causes increase in hardness [9]. Microcracks often appear on the cut plates surface and, when it comes to carbon steel, the surface oxidation occurs [5,7].…”
