Weldability of Heat-Resistant Material SAP by Method of Fusion

Abstract

Technology was developed for manufacture of SAP, possessing the ability to be welded by the method of fusion, and also technology of its argon-arc welding. Of all existing aluminum alloys, sufficient strength at a temperature of 350 - 5000 0 can be preserved only by material from sintered aluminum powder (SAP), the strengthening phase in which is oxide of aluminum. basic initial product for obtaining SAP is finely-dispersed aluminum powder which is obtained by atomization of liquid aluminum with compressed air, with subsequent crushing in ball mills in an oxidizing atmosphere.
