Abstract
The influence of thermal impact in nonconsumable electrode and electron beam welding on the features of cracking in different sections of the HAZ of high-strength complex-alloyed aluminium alloys V96 and V96tss at off-center tension has been analyzed. It is shown that the used temperature-time parameters of the welding mode change the volume fraction of particles contained in the alloy, their dimensions, shape and morphology of inclusion location on the boundary between the grains have an essential influence on the local stressed state in the HAZ metal and determine the associated mechanism of fracture site initiation.
