Re: [MW:5583] ASTM A 252 Grade 2 and 3

Dear Prasad

 

Thank You very much for your info.

I agree with you, as per API 620 the Fabircation code is ASME sec. IX. But as per singapore

regulations [NPQS]  and our QP's requirement is to follow AWS D1.1.

 

Again Thank you. Bye.

 

Best Regards

But you are telling the code of fabrication is AWS D 1.1

 

 

What ever may be code you can use SMAW or FCAW process.

 

You can weld ASTM A 252 Gr 2  to Gr 3 with E 7018 electode ( SMAW )  or E 71T1 or  E70T5 filler wire (FCAW process)

Dear prasad

 

Thank you for your reply.

 Fabrication & structural code is AWS D1.1. Tank is API 620.

Actually their issue is, "can we weld ASTM A 252 grade 2 and 3 together? if it is what 

filler can we use for FCAW or SMAW?."

 

Thank you for your support & Info.

 

Best Regards

Dear Sekar,

 

What is your code of fabrication. You can use E 7018 for SMAW and E 70S3 for TIG welding.
