Re: [MW:23998] Iron Dilution in 70-30 Cu-Ni W.D. on P-No. 1 Base Metal.

If you are analysing by spectro it should meet at 1mm. Otherwise you take chips from 1mm to 3mm and analyse the chemistry and prove it meets the requirement. In my opinion 5mm WD is required to meet 2mm undiluted weld.  Vanchinath

Dear Experts, 

Greetings of the day. 

 I need your expert advise on an issue. In one of our project, 70-30 Cu-Ni W.D. to be done on P-No. 1 base metal. As per client's Data sheet, 3.0 mm. W.D. is specified. Accordingly we have qualified WPS to get the undiluted chemistry on 3 mm. W.D. from interface as per ASME Sec. IX. But in client's project spec. it is specified- "in case a higher deposition thickness and multiple weld layers are required to achieve the minimum specified undiluted deposit metal, the same shall be done only after taking prior approval of client. Minimum thickness of undiluted finished weld overlay from top shall be 2 mm. or as specified in the drawing. Now, my concern is shall we have to certify undiluted chemistry at 1 mm. from fusion surface considering (3 mm. required W.D. as per Data sheet - 2 mm.) or at 3 mm. viz. top surface. 

Please revert at the earliest. 

 Thanks & regards, 

 C. R. GANDHI
