A novel experimental method was proposed to measure the mechanical melting point of A6N01-T5 aluminum alloy. Before test, characteristic parameters of thermal cycle were set according to the welding thermal cycle curves with different peak temperatures. The dimensions of sample were normalized. Based on thermal–mechanical simulation test, the dynamic stress data were acquisitioned and saved. The relationship between the residual stress and peak temperature was established. Based on the measured and predicted evolution of residual stress, the mechanical melting point of A6N01-T5 aluminum alloy was confirmed and validated.
