Abstract
This thesis deals with measuring perpendicularity and surface hardness free cutting edge technology, using flame from a total of 8 heats of carbon steel S235 to S460 in a range of thicknesses from 5 to 200 mm. The aim of this thesis is to verify if manufactured samples fulfill the norm EN 1090-2 + A1 or its part 6.4.4, which mandates a surface hardness thermally divided edges for steel S235 to S460 380 HV 10 and the norm ČSN EN ISO 9013.
