In this study, we present the results of electron-beam welding joints with 304-L stainless steel and copper. The influence beam’s power on structures mechanical properties welded was studied; experiments were realized at a beam deflection 0.3 mm to Cu plate powers 2400, 3000, 3600 W. phase compositions obtained studied by using X-ray diffraction (XRD); microstructure chemical composition invest...

The purpose of this study was to discuss the microstructure, recrystallization, and mechanical property evolutions in the heat-affected zones and fusion zones during dissimilar stainless steels welding. The morphology, quantity and chemical composition of the -ferrite were analyzed by using optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and ele...

Laser welding offers enormous flexibility in terms of delivered energy. It does however, require a vast amount of parameters and phenomena to be monitored in order to control the process and to ensure high quality processing. In laser welding the same depth of penetration can be achieved using different combinations of parameters, such as laser power, travel speed. The problem is further compli...

Minor problems arising from optimizations by welding of fixed prostheses frameworks can be identified by macroscopic and microscopic visual inspection. The purpose of this study was to highlight the visible discontinuities present in the laser welds of dental Ni-Cr alloys. Ni-Cr base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using cast plates, p...

Submerged Arc welding process is automated and semiautomated high deposition down hand welding process not vertical or over welding process, The fundamental difference of this welding process is that the Arc is not visible it is submerged into the flux. Weldment is fully submerged the heat loss is minimum and the thermal efficiency is very high up to 80-90%. A constant power sources and control...
