The paper presents the results of studying the features of weld formation at consumable electrode pulsed-arc welding of 4 mm AMg5M alloy in diff erent positions at the speed of 23 m/h. with forming backing element (FBE) and without it. It is shown that sound welds form irrespective of the angle of butt joint inclination relative to the horizontal plane. FBE presence increases the geometrical dimensions of weld made with consumable electrode by 4 – 12% on average, depending on the position of butt joints. Obtained data clearly demonstrates the possibility of achieving the required quality of welds and high level of mechanical properties in consumable electrode welding of aluminium-magnesium alloys at diff erent positions of the butt joints without FBE application. 6 Ref., 3 Tabl., 4 Fig. [ABSTRACT FROM AUTHOR] |
