问一个ndt的问题.

今天碰到ndt不合格,焊缝要返修,我想问一下,IACS关于焊缝返修的次数有没有规定?是多少次?DNV呢?小弟在这里先谢谢各位大哥了.

一般情况下，对同一部位的修补，从第三次开始需要报验船师－DNV
Rules for Ships / High Speed, Light Craft and Naval Surface Craft, January 2005 Pt.2 Ch.3 Sec.6 – Page 26
203 Repair welding in the same area may be carried out
twice. Further repairs shall be subject to agreement with the
Society.
但是从工厂生产角度和工艺角度讲，对同一部位的修补最多三次。
