Re: [MW:32264] welding api 5l x52 with x60

It is a normal practice in Pipeline to use low tensile electrode for the Root and hence you can use the WPS for welding X52 to A694 F60 as the requirement is the minimum Tensile strength as below. Check the PQR that 95% of UTS 67ksi (X52) is achieved.

For Piping, no issue.

Thanks & Regards

As per API 1104 , 2013 edn, Clause 5.4.2.2 , you can use the same WPS without requalification. I presume your flange and fittings are having same SMYS ( Specified Minimum Yield Strength)  and similar CEq

 

Requalification is required only when the base metal welding involves less than X42 or greater than X65. In your case this is not applicable.

 

Make sure, Your WPS have mentioned : Qualified Base material X42 Through  X60.

 

            Keeping future qualification purpose, it's better to qualify PQR with X65 material which many customers accept for all lower grades' base metal qualification.

Dear master 

i have a approved wps for welding api 5l x52  pipeline and i want to weld a anchor flange x60 is the wps cover it or we should requlaify it again
