Resumo
The paper presents manual narrow groove welding of marine high-strength titanium alloys of large thickness using special flat devices (nozzle burners), double-sided electron beam welding, and welding technology producing combined high-strength titanium alloys of large thickness (over 200 mm). Electron beam welding technology with filler wire in the vertical and horizontal position of the seam has been developed to fill the gap. The technology for repair of welded joints of titanium alloys of large thicknesses by electron-beam melting has also been developed. The mentioned technologies have been implemented at shipbuilding sites and have passed interdepartmental tests.
