AB  - In discussion of the welded joints from fracture mechanics point of
view, it is assumed that the welded joint is pre-cracked and that therefore fatigue life
of the pre-cracked structure is determined by the period of crack growth under
variable loading. Experimental data obtained by testing provide a substantial
foundation for better understanding and explanation of the phenomenon of fatigue of
a material. Low-cycle fatigue (LCF) occurs during charging and discharging of the
reactors, pressure vessels and pipelines; it can be accelerated by additional negative
effect of temperature variation and aggressive effect of vessel contents during
exploitation of the equipment in processing industry.
In present paper, the results of measurement of J-integral of weld metal made of
low-alloy high-strength steel, used for manufacture of the pressure vessels in the
process of powder welding, at LCF have been presented.

AB  - U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. Eksperimentalni podaci dobijeni ispitivanjem pružaju značajnu osnovu za bolje razumevanje i objašnjenje fenomena zamora materijala. Niskociklični zamor (LCF) se javlja u procesu punjenja i pražnjenja reaktora, posuda pod pritiskom i cevovoda; proces zamora može ubrzati dodatni negativan efekat promene temperature i efekat agresivne sredine sadržane u posudi, kao i tokom perioda eksploatacije opreme u procesnoj industriji. U ovom radu prikazani su rezultati merenja J integrala pri niskocikličnom zamoru (LCF) metala šava niskolegiranog čelika povišene čvrstoće (HSLA), koji se koristi u proizvodnji posuda pod pritiskom postupkom zavarivanja pod praškom.
AB  - From a fracture mechanics point of view on welded joints, it is assumed that the welded joint is pre-cracked such as that the fatigue life of the pre-cracked structure is then determined by the period of crack growth under variable load. Experimental data obtained by testing provide a substantial basis for a better understanding and an explanation of the phenomenon of material fatigue. Low cycle fatigue (LCF) occurs during the process of charging and discharging of reactors, pressure vessels and pipelines; the fatigue can be accelerated by an additional negative effect of temperature variation and the aggressive effect of the media contained inside the vessel, and during the exploitation of the equipment in the processing industry. In the present paper the results are presented of J-integral measurements at LCF of a low-alloyed high strength steel (HSLA) weld metal used in the submerged arc welding process in the manufacture of pressure vessels.

AB  - Istraživanje uzroka pojave prslina u zavarenim spojevi-ma je pokazalo da zaostali naponi doprinose otkazu rotornih bagera SRs 1300.26/5 + VR ± 10 u eksploataciji. Izvedena su ispitivanja radi karakterizacije zavarenih spojeva (hemijski sastav, zatezne osobine, tvrdoća i udarna žilavost čelika, elektroda i zavarenih spojeva) i ocene sklonosti ka pojavi prslina. Na osnovu teorijske analize radnih i kritičnih napona napravljen je model zavarene konstrukcije rotora bagera i određena su kritična mesta za merenje deformacija mernim trakama. Utvrđeni su zaostali naponi usled zavarivanja i radni naponi za različite režime rada rotornog bagera i analiziran njihov uticaj na otkaze u eksploataciji. .
AB  - The investigation of welded joint cracking revealed that residual stresses contribute to the failure of bucket wheel excavator SRs 1300.26/5 + VR ± 10 in exploitation. Testing for welded joints characterization (chemical com-position, tensile properties, hardness and impact toughness of steel, electrodes and welded joints) and susceptibility to cracking assessment had been performed. Based on theoretical analysis of working and critical stresses, a model of bucket wheel excavator welded structure was developed and critical locations for strain gauge measurements were determined. Welding residual stresses were assessed as well as working stresses for different operating regimes of excavator and their effects on service failures. .
