Dear Azhar

 

Your version "Spot Radiography is to be taken on joint but random examination is be selected from the lot"

 

I have the following comments :-

 

01.  In all cases the Radiography is always on the weld joints only

02.  Random is always from the different weld seams of a vessel

 

But the basic question is not yet replied.

 

May be Experts can shed some more light on this matter

 

Best regards
