摘　　要：铝合金特性显著,具有非常显著的耐蚀性,非常小的密度小,非常好的导热和导电性能等,所以在使用的过程中具备属于自己的独特优势,并且在工业领域当中得到了非常广泛的使用。现阶段,我国钢铁的产量排行第一,而排在第二的则是铝合金的产量。铝合金焊接接头拉伸性能对于选择的是哪一种焊后处理工艺有着非常严格的标准,因为焊后处理工艺的选择会直接影响到接接头拉伸性能的高低。对于焊接结构来说,铝合金的拉伸性会直接影响到铝合金疲劳,甚至影响到其使用寿命。所以,本次研究对焊后处理工艺做出了详细的分析,主要的目的就是促使铝合金焊接接头拉伸的性能得到最大程度的改善。Aluminum alloy has remarkable characteristics,corrosion resistance,very small density,very good thermal and electrical conductivity,so it has its own unique advantages in the use process,and has been widely used in the industrial field.At present,the output of iron and steel ranks first in China,while the output of aluminum alloy ranks second.The tensile properties of aluminium alloy welded joints have very strict criteria for which post-weld treatment process to choose,because the selection of post-weld treatment process will directly affect the tensile properties of the joints.For welded structures,the tensile properties of aluminium alloys will directly affect the fatigue of aluminium alloys,and even affect their service life.Therefore,this study has made a detailed analysis of the post-welding process,the main purpose is to promote the tensile properties of aluminum alloy welded joints to the greatest extent.
