The invention discloses a method, a system, a medium and equipment for automatically recovering missing data items of a circumferential weld, and relates to the field of circumferential weld failure risk data processing. The method comprises the following steps: constructing a sample vector matrix comprising sample data of complete data items; constructing a first failure data vector comprising the missing data item; calculating a preset correlation function according to the first failure data vector in combination with the sample vector matrix; calculating missing data items according to the preset correlation function; and the missing data items of the circumferential weld are recovered according to the calculated missing data items, and the missing data items can be rapidly recovered by fitting coefficients of typical samples of the circumferential weld of the missing data items and utilizing the fitting coefficients and the typical samples. And the circumferential weld which cannot be subjected to risk pr
