摘要
对2 mm厚的01420铝锂合金薄板实现了搅拌摩擦焊接(FSW),分析焊接接头的微观组织形态,研究焊接工艺参数对搅拌摩擦焊接接头成型和接头性能的影响,并与氩弧焊接接头性能相比较。结果表明,当工艺参数选取得当时,焊缝成型较好,表面光洁,焊接接头的强度可达到母材强度的77%,接头的弯曲角可达到180°,均高于氩弧焊接接头。
The friction stir welding of 2mm thick 01420 Al-Li alloy was conducted, the mierostruetures, qualities of joining, and mechanical properties of the joints as well as the influences of welding parameters on the alloy were investigated, meanwhile comparing the mechanical properties with that of the joint welded by argon arc welding. The results show that if the welding parameters are optimal, good appearance welds are achieved, the tensile property of weld can attain 77% that of the base metal, and the bending angle can reach 180°, which is higher than those of the joint welded by argon are welding.
