In general, plasma cutting speed is faster than gas cutting speed. However, It is known that quality of plasma cutting is bad for thick plate 30 mm or more. And plasma cutting is difficult to cut steel plate for 50 mm or more. The purpose of this study was to find out the worsening cause of cutting quality for 30 mm or more thick plate cutting. This study observed the form of the cut and the metallic organization of cross section in the heat affected zone. We found that the flow of molten metal was influenced by the cutting conditions during plasma cutting through experiments. Also we were able to recognize the impact of the quality of the cut by the shape of the cut and HAZ depth.
