| Abstract: | Investigations were carried out into the production of combined welded joints in 316L(N) austenitic steel and BrKh1Tsr (CuCrZr) and CuAl10Ni5Fe4 bronzes 30 mm thick by electron beam welding (EBW). The formation of the welded joints in dissimilar materials is investigated and the EBW conditions determined. The microstructure, mechanic properties and chemical composition of the welded joints are also determined. It is shown possible to obtain the mechanical properties of welded joints similar to the properties of the parent bronze by weldbrazing. It is therefore necessary to increase the accuracy and stability of the electron beam parameters as a technological tool. |
