A comprehensive study has been made of the destruction of welded joints of the titanium alloy VT20 of a Ti–Al–Zr–Mo–V system and high-strength aluminum–lithium alloy V-1461 of an Al–Cu–Li system. The welds were obtained by the method of laser welding with different values of displacement of the laser-beam path from the butt joint of the materials in the direction of the VT20 alloy. On the basis of mechanical tests, recording of the process of destruction of the welds in the infrared range, and analysis of fractures using scanning electron microscopy (SEM), and energy-dispersive x-ray spectroscopy (EDX), the authors have established a value of displacement of the laser beam, at which best mechanical properties of the weld are attained, and also the elemental-phase weld structure corresponding to these properties.
