Electron Beam Welding of Titanium and Stainless Steel with Copper Interlayer

Popis výsledku v původním jazyce

This paper deals with the welding of heterogeneous materials to produce a mechanically resistant weldment. An innovative welding process was chosen, called electron beam welding. Titanium UNS N50400 with austenitic stainless steel X5CrNi 18-10 was welded. During welding, titanium must be protected from the absorption of air gases, which negatively affects its quality. Therefore, welding was carried in a vacuum. Another problem with titanium and stainless steel welding is that brittle compounds are formed without an interlayer. These compounds highly negatively affect the weld quality and make it impossible to implement it. Therefore, it is necessary to select a third material as an interlayer. Copper was used for the above-mentioned interlayer. Tensile strength was measured to evaluate weldment quality. To determine the chemical composition of the weld, spectral analysis was performed on an optical spectrometer. An electron microscope micrograph was taken to visualise the weld.
