Research ArticleOpen accessPhrase in the titleA Review of the Fatigue Strength of Load Carrying Shear Welded JointsFilippo Berto, Abedin Gagani, Relly Victoria V. Petrescu, Florian Ion T. PetrescuIn the study it is shown an overview of the latest results of two types of joints of the load carrying welded shear. Tests of fatigue have been carried out on the two solutions specific design features proposed and with the aim of improving the resistance of the joints under cycling loading. By hiring the 3D models, was determined Strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 2 Jan 2017 · 7,731 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,599 accessesView PDF Cite
