Re: [MW:30322] Filler material Selection

Received clarification from the client about using E316L to weld Carbon steel.

Their welders are qualified to weld steel (P1 to P15) with filler material (F1 to F4).

They want these welder to be qualified for F No. 5 but do not have austenitic steel base metal in stock. Only Carbon steel is available in stock.

Therefore, they have requested a PQR to weld Carbon steel base metal P No 1 with E316L and ER 316L (F5 and F6).

In case the coupon meets ASME Section IX Nondestructive and destructive testing requirements, they will prepare a WPS which shall be used only to qualify welders for F number.

On another note, I hope to receive guidance on selection of filler materials in general. 

What are the parameters to be considered to select filler materials for any base metal and whether it is addressed by general standards in the industry.

Thanks and best regards,

Navanith

Possible, yes, but not for Section I if water wetted service.

 

Practical, no, absolutely not.  I have a really difficult time trying to come with any reason to do this and a host of possible issues if done.

Dear Experts,

 

Require guidance on filler material selection as per ASME BPVC.

For example:I received this query from a client

Base metal is ASTM A106 Gr.B and they want to weld using E316L electrodes.

Is it possible to use E316L electrodes to weld directly?

 

Regards,

Navanith
