Modelling of thermal processes in a dissymmetrical welded cast aluminium designs

Abstract

Number of constructions, produced from eutectic silumins are continually increasing, therefore problem of their welding became very astual. Eutectic aluminium - silicon alloys are sensitive to changes of a welding thermal cycle. These cast aluminium alloys constructions after welding have large residual stresses, and mechanical properties of welded joint deteriorate. [...].
