| 摘 要： | 依据焊接缺陷评定标准PD6493-8O,CVDA-84,JWES-2805,关于从球罐钻取的深埋夹杂与气孔的实验和金相研究,对于多台球罐最大表面裂纹的断裂力学评定,并鉴于修补这类缺陷占总修补量的70～80%,我们认为放宽气孔与夹杂的验收标准是妥当的

| Abstract: | According to the acceptance standards for welded defects PD6493-80 , CVDA-84, JWES-2805, relying on The result of experimenting and metallurgy study of picking furied slag inclusios and the porosities in spherical tanks,and on ihc frac ture mechanical a ssessmen Is of the largest Cracks" in the tanks and considering that the amount of repairing the defects is some 70-80% of the total amount We think it would be better to relax the acceptance standards for porosity and slag indusro ins. |
