摘要 采用ER4043,ER4047铝硅合金焊丝对AZ31镁合金和7005铝合金异种材料进行填丝钨极氩弧焊(GTAW),并对AZ31/7005接头进行微观组织观察和显微硬度分析。结果表明:采用填丝钨极氩弧焊工艺,可以获得表面成形良好的焊接接头;镁侧熔合区是接头力学性能的薄弱区,镁侧熔合区不同结晶区域Mg和Al的成分较为接近,组织主要为Mg17Al12+Mg共晶体组织;靠近镁侧熔合区无高硬度脆性相产生,焊缝区的硬度稍高于镁母材区,但远低于铝母材区。

Abstract:AZ31/7005 dissimilar materials were welded successfully by using gas tungsten arc welding (GTAW) with ER4043 and ER4047 welding wire of Al-Si system. Microstructure of the joints was observed and microhardness of the joints was analyzed. The results indicate that joints with good surface and free defects are achieved by GTAW.The fusion zone near magnesium side is the weak zone for mechanical performance of the joints. Contents of Mg and Al keep stable in the fusion zone near magnesium. The fusion zone is mainly composed of Mg17Al12+Mg eutectic microstructure. There is no obvious high hardness brittle phase in the fusion zone near magnesium side. The hardness of joints is slightly higher than that of Mg base metal, but far less than that of Al base metal.
