摘要
铝合金由于热膨胀系数较大,导致焊接变形严重。因此,为了减少焊接变形,研究对6061-T6铝合金的焊接变形情况进行了分析,并进一步研究了施加控制措施后的铝合金薄板变形情况。实验结果显示,进行电子束叠焊时,铝合金薄板中心区域的变形量最大,且实测变形量始终小于仿真变形量。这是因为实验时对薄板使用了夹具夹持,而在施加反变形或刚性约束后,薄板的变形量明显较少,且与原变形方向相反。上述结果表明,通过反变形法或刚性约束法能有效减少铝合金的焊接变形量,且刚性约束法的控制效果更好。
Due to the high coefficient of thermal expansion,aluminum alloys suffer from severe welding deformation.Therefore,in order to reduce welding deformation,an analysis was conducted on the welding deformation of 6061-T6 aluminum alloy,and further research was conducted on the deformation of aluminum alloy thin plates after applying control measures.The experi⁃mental results show that during electron beam overlay welding,the deformation in the central area of the aluminum alloy thin plate is the largest,and the measured deformation is always smaller than the simulated deformation.This is because a fixture was used to clamp the thin plate during the experiment,and after applying reverse deformation or rigid constraints,the deforma⁃tion of the thin plate is significantly less and opposite to the original deformation direction.The above results indicate that the anti deformation method or rigid constraint method can effectively reduce the welding deformation of aluminum alloys,and the control effect of rigid constraint method is better.
