摘要

Mechanical properties and features of fracture microrelief in welded joints of 1201 aluminum alloy, obtained by constricted arc welding at different speeds (24–120 m/h), were studied. The joint ductility is the highest when welding at a speed of 24 m/h, and energy-intensive pit microrelief and deformation ridges are formed on the fracture surface. The strength of joints in this case slightly decreases, but their ductility increases.
