Abstract

A retrospective of the use of heat-resistant aluminum alloys of various alloying systems is presented, possible prospects for their applications are considered. The general problems of weldability of these alloys are indicated. The analysis of the causes of hot cracks in welded joints is carried out, methods and approaches for their elimination are considered in detail. The weldability of heat-resistant aluminum alloys 1151, B-1213, AK4-1ch. and 1201 with and without filler wires was evaluated.
