Sažetak
The paper describes mechanical testing on specimens made from 13CrMo4-5 boiler steel and numerical analysis based on conducted experiment. During magnetic particle testing (MT) examination of weld on the bottom header of a front wall of boiler large amount of indications (cracks) were noticed. In the experimental part of paper tension test was conducted in order to determine basic mechanical properties of specimens. After that, bend testing was conducted to determine an angle on which cracks occur, and ultimately fracture. In order to compare obtained results with results obtained experimentally, 3D model of specimens was created, and numerical analysis by finite element method (FEM)was carried out. Analysis of results has given guidance for further examinations, assuming that they will ultimately give an answer on type an incurred cracks.
