摘　　要：针对大尺寸5A06-H112厚铝合金板实心吊框的成形,采用了60mm铝板折弯拼焊后进行机械加工的工艺优化路线,并对5A06厚板的折弯和焊接工艺进行了研究。通过有限元计算,及对实心框静力加载进行的试验和分析证实,采用MIG焊接成形的铝合金实心吊框的力学性能完全满足使用要求。结果表明,采用MIG大电流多道焊工艺,可以保证焊缝接头强度达到母材的90%以上。组焊而成的实心吊框与整体机加框在载荷范围内有着大体相同的结构力学性能,但整体机加框储备了更多的塑性以应对可能的脆性失效。：In view of large size of 5A06-H112 thick aluminum alloy plate solid frame forming, the process optimization route of bending welding after machining for 60 mm aluminum plate was adopted. And the bending and welding process for the 5A06 plate was researched. Through FEM and static mechanical experiment proving, the mechanical properties of welded structure of aluminum alloy box sling frame adopting MIG welding can meet the usage demand. The results show that adopting MIG by the strong current, the multi-layer welding process reaches more than 90% joint strength compared with base metal, and the mechanical properties of welded skeleton is the same as that of the whole skeleton, but the whole one has the more plastic capacity to prevent brittleness invalidation.
