摘　　要：建立了7A05铝合金焊接热影响区强度折减模型，并在此基础上提出了考虑焊接热影响区的铝合金焊接结构强度计算方法。实验结果表明，该方法的理论计算值与实验值误差小于2％，与现行计算方法相比，计算结果更接近实际。The model of strength reduction in welded heat affected zone of 7A05 aluminum alloy is established, and a new method for calculating the strength of welded aluminum alloy structure is presented based on this model. The experiment shows that the error of this method between the theoretical calculation results and the experimental results is less than 2 %. Compared to the current calculating method, this method is much closer to the actual one.
