Abstract
Technological features of automatic one-sided consumable electrode pulsed-arc welding in argon of butt joints of sheet aluminium alloys AMg6 and 1915T up to 3 mm thick without application of forming backing elements («gravity» welding) were studied. Influence of welding mode parameter modulation on the geometrical shape of welds and their macrostructure was shown. Recommendations on «gravity» welding technology are given.
