We have imported this vessel from Germany but during 3rd party inspection it is rejected because of this undercut. The working pressure of this vessel is only 3.5 bar and its successful withstood a hydro test pressure of 10 bar.

Now I request all the expert to please advice if we can repair this undercut if yes than please provide me some guideline or some procedure to carry out this repairing.

Thanks in advance for your kind help.
