| 摘 要： | 针对2A14、2219、2195、2A97、1460铝合金,通过焊接热模拟试验、焊接裂纹敏感性试验和拉伸试验,建立了材料脆性温度区间大小和焊接性的关系及焊丝主成分和焊接性的关系。结果表明,试验合金焊接性从好到差的排列顺序为2219、2A14、1460、2195、2A97。其中2A14、2219铝合金现用焊丝可以满足推进剂贮箱用铝合金焊接性要求。脆性温度区间较小时,焊接性良好,随脆性温度区间增加,焊接性变差;采用满足主成分含量之和为6%的焊丝焊接时,若抗裂性满足要求,则接头延伸率满足要求。 |
| 关 键 词： | 铝合金 焊接裂纹敏感性 接头延伸率 |

| Abstract: | Through experiments of welding thermo-simulation,welding crack sensitivity and tension on aluminum alloys marked 2A14,2219,2195,2A97,1460, relationships between BRT and weldability,total content of main elements in welding wire and weldability are established. Results show that the less BRT, the better weldability; when 6% of total cintent of main element is used in the welding wire,joint elagation will be eligible if the ability anticrack is good. Rank of weldability is 2219,2A14,2195,2A97. |
| Keywords: | Aluminum alloys Welding crack sensitivity Joint elagation |
