| description | The invention relates to a method for improving the flaw detection qualification rate of an aluminum alloy ring piece finished product, which comprises the following steps: flaw detection is carried out after the surface of a forged ring blank is exposed to light to obtain a first threshold value and a second threshold value of a flaw detection unqualified area; obtaining a first outer diameter, a first inner diameter and a first height dimension; if the first inner diameter is larger than the first threshold value, it is judged that flaw detection of the ring piece finished product is qualified; if the first inner diameter is smaller than or equal to the first threshold value, it is judged that flaw detection of the ring piece finished product is unqualified, and a flaw detection unqualified area is reversely deduced and checked; and the forging process parameters are adjusted again, new forging process parameters are obtained, and the third threshold value of the adjusted flaw detection unqualified area is |
