通过试验对比了不同状态下2519/5A06异种铝合金熔焊焊接接头的力学性能。分析发现,采用热输入小的脉冲氩弧焊时,焊接接头力学指标离散度较大,并且强度较低。增加辅助随焊捶击后,虽然焊接接头力学性能稳定,但强度提高不明显。而采用A-TIG方法焊接时,焊接接头力学性能明显提高。
The mechanical properties of 2519 / 5A06 dissimilar aluminum alloy fusion welded joints under different conditions were compared. The analysis shows that when using small pulse TIG welding heat input, the weld joint mechanical indicators greater dispersion and lower intensity. Increasing the auxiliary welding thump, although the mechanical properties of welded joints stable, but the intensity is not obvious. The A-TIG method of welding, the mechanical properties of welded joints improved significantly.
