SELCTION FILLER METAL FOR WELDING SA 213T22 WITH SA192 2

[Figueredo]

Hi to all

i have a question about selection of filler metal, SA213 T22 AND SA 192

1 OPTION ER80S-BL2

2 OPTION ER70S-BL2

3 OPTION ER70S-2

WHAT IS THE BEST FILLER METAL FOR A GOOD WELD?

THANKS FOR YOUR HELP...

What Code are you working to? (what strength and creep properties do you need)

Based on what you have provided, I would use ER80S-B2. The B2L is low carbon filler and should not be used for this type of application.

IS A WELDING FOR SUPERHEATER PIPE (WE MAKE REPLACE OF PIPE AND OUR WPS FOR A WELDING P1 WITH P4 THE FILLER METAL IS ER80S-BL2 IF A METAL BASE SA 213 T22 HAVE 1/2% CR AN 1/2% MO THE FILLER METAL MUST BE CONTAIN BETWEEN 1 OR 1 1/2% CR AND MO IS MY APRECIATION FOR EQUALIZATION FOR CHEMICAL COMPOSITION.

There is no such designation for BL2, it is B2L. For pipe butt welds, use of low carbon filler metal is not recommended. Second, ER80S-B2L is no longer supplied because the L grade have been re-assigned strength values after PWHT. Former ER80S-B2L is now ER70S-B2L.

guys

The super heater tube working high temp. around 320 a 424°C is a necessary make pwth after construccion weding process? i think is not necessary.

Thanks for you helps.

PWHT is based on thickness of the base materials in Section I ASME B&PV Code. What is the thickness of the tube?

0,125"

PLEASE SEE THE INDEX SCKETH

 

[metengr]

PWHT is not necessary.

Just as a side note, API RP 577 and RP 582 might be useful in filler metal selection for general purpose. Not sure of this would fall under that scope.

You could also consider ER70S-A1 for the service in addition to metengr's recommendation. I would not recommend ER70S-2 or other low carbon steel filler metals for the service (nearly 800 F).

Thanks Weldstan, is much better this filler metal for %C is 0,12 but if necesary make new one PQR with this filler metal. i have wps with filler metal ER80S-B2L is so old have 15 years.

Thanks to all
