The dynamic processes happening in the welded seams received by welding by the highconcentrated power sources are of considerable interest. Change of the intense deformed state in ring welded seams is considered. The maximum ...
Results of numerical modeling of formation of a final chemical composition at electron beam welding with oscillations and dynamic splitting of an electronic beam on three thermal sources are presented in this article. Verification ...
This paper presents the results of study of electron beam welding (EBW) of thin sheet niobium. The review of published data on EBW of niobium for superconducting radio-frequency (SRF) cavities was done. Relations between EBW ...
The mathematical model describing distribution of temperatures at electron-beam welding with beam splitting on three is presented. At the heart of model construction the analytical solution of problems of a thermal conduction ...
The direct and inverse problems of keyhole shape reconstruction through the accompanying Xray bremsstrahlung were formulated. It was shown that the inverse problem of reconstruction of channel penetration is reduced to the ...
Electron beam is at the forefront of welding technology. The choice of optimal welding modes, monitoring the weld quality and/or detecting weld defects in real-time during the electron beam welding process using nondestructive, ...
The electron beam technology allows a rapid scanning along a defined trajectory. When a properly controlled input of energy is applied, it could be used for the manufacturing of a whole weld joint at once. This technology, ...
In welding technology, the change of state from solid to liquid back to solid is used for safe joining using a localized effect of heat. Due to the thermal expansion, as well as due to structural transformations the outcome ...
In dissimilar welded joints without filler materials, the positioning of the electron beam is one of the most crucial factors in controlling weld quality. Among other factors, the small beam diameter and a highly accurate ...
