Abstract
Efficient control of laser cutting processes is closely related to knowledge of heat effects in the cutting front and its surroundings.
The macrographs show that the majority of the cuts shown can be classified in the highest quality class considering the machining conditions specified. This proves that in the case of austenitic stainless steel, the cutting speeds were suitably chosen for the particular material thicknesses. The variation of the HAZ thickness indicate that in the bottom part of the cut more intensive chemical processes are occurring between the molted material and the oxygen gas, hence heat is released. In the bottom part of inclined the cut, due to flow of the melt, heat from the melt is additionally transferred into the cool surroundings of the cut.
