Abstract:
Results of an experimental study of properties of joints obtained by using different regimes of laser welding of the $1424$ alloy $(\mathrm{Al}$–$\mathrm{Mg}$–$\mathrm{Li})$ are reported. The strength and structure of the welded joints are determined. The influence of various types of welded joint straining on its strength is studied. It is demonstrated that the joint strength increases in the case of plastic straining.
