We did an RT to verify the presence of IFD . But not getting IfD on RT. 

In addition we noticed bright indication , which may be cupper pick up in root. 

Client representative  interpretated this  as Cupper Pick Up

Experts pls advice.

I read the comments.

Why don't you correct your welding procedure...?

All these discussions aside, finally your meat is under your client's teeth.

So I recommend you first to correct the issue. This way you will have more of your client support.

But if you don't and just try to justify, it will make them more upset. Believe me, I have been the client's inspector all my career.

Tell me about the welding procedure.

Dear All,

Our Pipeline specification not accepting Incomplete Fusion .In case of incomplete fusion weld shall be rejected and re-welded.

But according to API 1104, IF and IFD are different . So is it required to reject both IF and IFD as both are incomplete Fusion?

Please help me with advice 

I am using AUT for the inspection and 70 % of joints are detecting either IF or IFD 

With Regards

Riaz 

Pls help me
