I don’t understand why the PQR can’t be used in Future. Please give specific reason. Is it because we are not putting brand name / SFA or AWS Specification of Filler wire in WPS/PQR ?
Now what I have come to know for the origin of this Filler wire is quite strange. Actually the person who procured the Filler metal, is a director of the company, and he does not want to disclose the brand name of Original Wire Rod of Dia. 5.5 mm as a part of trade secret. He informed me that he has procured the wire rod from a Company A & drawn the same at a Company B. He has given me name of both companies, but did not give exact brand name.
Now the problem is I can mention only the manufacturing company-A (Wire Rod Dia. 5.5 mm) name on WPS/PQR, and not exact brand name. There is no point of using name of Company-B, which has just drawn the Wire rod into Dia. 1.1 mm wire.
Even if he gives me the brand name of the Dia. 5.5 mm Wire Rod, then also how can I write it on WPS/PQR, because actually he has drawn the same to Dia. 1.1 mm wire, which is not having any brand name.
Can you give me any suggestion how to deal with this situation ?
The second option is to find out the AWS or SFA specification for chemical composition of Alloy 825 (UNS N08825). I tried very much, but perhaps there is no AWS or SFA Specification for the composition (Nickel 38 to 46%, Cr. 19.5 to 23.5%, Moly 2.5 to 3.5%, Ti 0.6 to 1.2%). If you know the AWS or SFA No. for the same, then please let me know.
This may be the reason for that person to keep it secret, because he told me that he has ordered the wire rod having such specification specially.
I have tested the Corrosion Resistant Overlay Test piece successfully in all respect for Side bend, Chemical Analysis and DP Test. Only problem is how to write WPS/PQR in absence of proper AWS/SFA specification or brand name ?
