Re: [MW:25641] Re: Base metal qualification range of unlisted material as per AWS D1.1

Hi Amjad,

Sorry. This is the MAIN Issue when AWS D1.1 is used for qualification. I wonder why this code is of such a narrow scope with regards to materials.

Yes, 

a. you need to requalify for J2 Material.

b. If client accepts, Please try performing Impact test of the material per J2 requirements, if successful, it may be recertified to J2 for the particular product. also ensure the chemical properties match J2 Requirements.

c. Ask for concession to use the same WPS from the client.

The main reason I prefer to go per EN ISO 15614 in lieu of AWS D1.1 is this narrow range of materials. EN limits the range based on Material Yield strength not by the designation.

Thanks and Best Regards,

K.Rajagopal

Thanks a lot for the response sir, That was the exact doubt i was having , as  S355 is un listed in AWSD1.1  ,  also The only diffrence between S355J2 and S355JR is the impact test requirement . other properties are same .

If a wps is qualified in base metal S355J2 will it be qulified for S355JR Code AWS. I have WPS qualified with base metal S355J2  but now due to stock availability only S 355JR is available can i use same WPS for this one also . as only the grade is changing
