Sažetak
According to the technical documentation received from client, weld defect in butt weld according to the EN ISO 6520-1, Series 400 is considered. It is found that there are several joints with the same weld defect, but only the most critical is analysed. Model is analysed for calculating and testing conditions, whereas for testing conditions two cases are analysed: testing conditions according to the EN and testing conditions with maximal allowable pressure. Mentioned weld defect is considered as non-standard crack (failure), so the crack tip is defined as stress concentration. Furthermore, creep diagram is constructed according to the values of creep rupture strength for 200 000 hours from EN 10216-2:2002+A2:2007 (E). Based on that norm, for material used in construction and for temperature conditions, it is found that creep does not occur, but anyway, trend line is constructed in order to find the value of creep rupture for considered conditions.
