Hodnocení vybraných vlastností svarového spoje nízkouhlíkové oceli zpracované vícenásobnou plastickou deformaci

Abstract

This bachelor thesis examines the influence of welding to weld low carbon steel processed multiple plastic deformation. The introduction describes a method DRECE for the production this treated steel and also techniques for suitable welding method for this type of material. Experimental section is devoted to examining the influence of welding residual stresses by analysis, examining the weld macrostructure and microstructure and microhardness. The conclusion is the evaluation of the influence of welding based on a comparison of the measured values of microhardness, residual stress analysis, evaluation and comparison of the structures arising due to welding.
