Bakalářská práce se zabývá tuhostí prefabrikovaných spojů a jejich vlivem na statické schéma. Najdete zde rozdělení spojů podle různých kritérií: dle tuhosti, provedení a přenosu vnitřních sil. Jsou zde obecně popsány možnosti provádění spojů prefabrikovaných dílců, kloubových i tuhých. Práce se zabývá návrhem styku spojitých průvlaků v místě sloup...
The full benefits of application the high strength low alloyed steels HSLA can be achieved if the structures will be able to carry the alternate loads and fatigue cracks will not be formed, even in the vicinity of welded joints. For this reason the purpose of this study is to find and to explain the influence of different factors on fatigue crack i...
Structural geometry and stochastic loads such as swell and wind seas can typically induce multiaxial stress states in welded details of marine structures. It is known that such complex time varying stress states determine the fatigue resistance of welded steel joints. Therefore, it is of importance to account for them in fatigue lifetime assessment...
Tato bakalářská práce zkoumá rozdíly v kvalitě smaltového povlaku na svarovém spoji při použití různé předúpravy povrchu. Nejprve nás seznámí se svařovací částí, kde je zjištěna svařitelnost materiálu a poté je zvolena vhodná svařovací technologie. Za touto částí následuje část o samotných smaltech, kde jsou popsány jejich vlastnosti, jak se vyrábí...

AbstractPhase transitions during crystallization and subsequent thermal and deformation effects under the influence of various mechanical loads in welded joints of the plates of medium carbon steel by a consumable electrode in shielding gases with a flux-cored wire based on Fe–C–Cr matrix are studied. The test results for weldability, abrasive wear...

The article presents a methodology of non-destructive diagnostic vibratory tests of welded plates with geometrical parameters that classify them into a group of thin-walled panels. On the basis of such plates, most ship constructions are created. In previous works, the authors dealt with the study of welded joints in plates with significant thickne...

AbstractThe paper shows the research results of the structure and mechanical properties of welded joints of the hot-pressed panels and profiles manufactured by JSC Arkonik SMP from aluminum–magnesium 1565ch alloy at the temperature range from –165 to 150°C. It is established that the nature of changes in the properties of welded joints of pressed p...
Turret structures within FPSO's are subjected to a variety of repeated loads, due to the harsh environment they operate in during their service live, meaning that fatigue is a governing limit state in turret structural design. Turret structural components are connected by arc-welded joints which are considered particularly susceptible to fatigue da...
Residual stresses can affect both the static strength and the fatigue endurance of welded joints. Residual stresses can be assessed by numerical simulation / however, the simulation of the welding process is a complex task that requires knowledge of several parameters, many of which can only be estimated with some uncertainty. The reduction in the ...

Abstract—Thick rolled products (plates) made of high-strength S690 steels (σy ≥ 690 MPa), which have not been used in the Russian building industry to date, are shown to be used in bearing welded metallic structures. Technological approaches, which can impart the high service properties that meet the requirements of norms and records to thick-sheet...
