RT Journal Article SR Electronic A1 Zrak, Andrej A1 Koňár, Radoslav A1 Jankejech, Peter T1 Influence of Chemical Composition in Steel on Laser Cutting Stability JF Manufacturing Technology Journal YR 2015 VO 15 IS 4 SP 748 OP 752 DO 10.21062/ujep/x.2015/a/1213-2489/MT/15/4/748 UL https://journalmt.com/artkey/mft-201504-0052.php AB The translation in this article analyses the technology of laser cutting, describes properties of laser cutting equipment the oxidation process of melting and sublimation laser cutting. In the article chemical composition of cutted material in the interaction with the quality of cutting edges from cut-outs is analysed. The measurement was performed on experimental samples made from steel grade S355 however the composition of chemical elements in each sample varied. On these experimental samples the cutting edges was examined for the purpose to find out the influence of chemical purity of material on the quality of components which were cut by using laser technology.
