| Abstract: | This article take the major technique parameter of the large-scale welded revolving canister as the basis, to analyse and judge the fatigue failure spot and the reason of the large-scale welded revolving canister＇ seam.By calculating analysis, verifying and building logic analysis method, find out the failure mode of the large-scale welded revolving canister. Thereby, the main approach to prevent the invalid was brought for ward, which provide the reliable basis for the design, manufacture of the large-scale thickening revolving canister. |
