Abstract

Mechanical properties and features of fracture microrelief in welded joints of 1201 alumi­nium alloy, produced by constricted arc welding at different speeds (24–120 m/h) were studied. When welding at the speed of 24 m/h, the joint ductility is the highest, 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.
