dcterms:description
Use of sheets and products made of them is very extensive. That’s why high demands are made on them from the viewpoint of mechanical load, resistance to corrosion in various environments, structural properties, etc. After rolling followed by technological processing the sheets are prepared for customers in the required dimensions and shape. This process often uses cutting units based on heat (flame) cutting by oxygen or plasma. This type of cutting creates a thermally influenced area at the place of cutting as a result of thermal effect of flame, and it can thus cause degradation of the mentioned properties at the edges of the sheets or shaped cut-out pieces. Such damage can be further amplified during subsequent treatment, e.g. at welding of the shaped cut-out pieces. The objective of the work was to determine in what extent plasma cutting influences the cut edges of the semi-products, and whether in these areas such changes occur, which would be fundamentally reflected in mechanical and other properties of the product, as well as how wide is the heat effected area from the material edge, which must be taken into account at further processing or at technological processes used for fabrication of the product.
