摘　　要：采用4043与5356焊丝为填充金属对体积分数为10%~15%SiCp/6061Al复合材料进行TIG焊,通过焊缝外观成形、金相分析与拉伸试验,对焊接接头进行了分析。结果表明4043焊丝在焊缝成形、改善熔池流动性、提高接头力学性能等方面均优于5356焊丝,但是焊缝中缺少增强相,最高接头强度只能达到母材的56.7%。Taking 4043 and 5356 wires as filler metal, SiCp/6061A1 composite with the volume fraction of 10 %-15% was welded by TIG. The weld appearance, metallographic analysis and tensile test of the welded joint was analyzed. The results show that： the effect of 4043 wire is better than that of 5356 wire on improving the liquidity of weld pool and mechanical properties of the joints. Because of the lack of reinforcing phase in welded joint, the highest joint strength of the samples can reach 56.7% of matrix.
