Abstract

The results of a study of the welding properties of new aluminum alloys Al–1,0Ca–5,5Zn–1,5Mg–0,5Mn and Al–2,0Ca–2,5Mg–0,4Mn are presented. The mechanical properties of the studied alloys in argon arc and laser welding are determined. The power of Al-1,0Ca–5,5Zn–1,5Mg–0,5Mn and Al–2,0Ca–2,5Mg–0,4Mn alloys to the formation of pores in the seam in fusion welding is viewed.
