METHOD OF MAKING WELDED STRUCTURES FROM ALUMINIUM ALLOY CASTINGS

摘要

FIELD: process engineering.SUBSTANCE: invention may be used for making welded-sheet structures for aircraft applications. Proposed method comprises machining cast part edges before welding by friction welding and mixing. Then, edges of parts to be welded together are mechanically processed. Note here that said strained structure is formed in said high-temperature zone of cast part thermal effects.EFFECT: welded structure composed of cast parts, or structure including cast part welded to sheet that features strength not lower than that of cast part.4 dwg, 3 tbl, 2 ex
