The influence of welding speed (23, 40 and 57 m/h) under the conditions of the action of a consumable electrode on the nature
of free penetration and crystallization of welds of AMg5M alloy in different spatial positions of butts was investigated. It was
established that the optimal thermophysical conditions for the formation of a fine-grained structure of the joints occur when
the welding speed is 40 m/h. At the same time, the strength of the welds increases by 10…15% without reducing the level of
ductility. A distinctive feature in the structure of welds produced at different welding speeds is the size and shape of dendrites
and phase inclusions in the intercrystalline space. 6 Ref., 5 Tabl., 1 Fig.
