A 217 Gr WC9

[Luis Carlos]

Hello,

Could someone tell me please what is the best filler metal to make a
buttering over A-217 Gr WC9 base metal.

Are there special recommendations?

I will appreciate answers!

Hi Luis,

The material is 2.25Cr-1Mo steel (P 5A Gr 1)  in the shape of casting. What' the other material to be welded? A rule of thumb could be :-

• A 217 Gr WC9 to P4 material-- Use P4 matching electrode for buttering, e.g-E 8018/16 B2 or E-7018B2 or GTAW filler of equivalent specification. You may use E-9018B3 or 8018B3L also, in that case buttering sequence may not be needed.

 

• A 217 Gr WC9 to S.S- Use Inconel-182(E NiCrFe-3) or matching GTAW filler(ERNiCr-3) for buttering.PWHT the buttered area and   P5 steel as recommended by design code followed by welding to P8 without further PWHT.
  

Note the above guidelines are only generalized rule. Buttering sequences and welding electrodes to be used would depend on what material gets welded to A 217 Gr WC9 and the code or specification requirements.

 

Note the  precautions and welding parameters to be followed for buttering shall be identical to a groove  weld.

 

Thanks.

Hi Luis, I hope the attached Bohler data sheet will be useful. Please let me know if you found in it what you looked for. Thanks, Shashank Vagal --- On Mon, 30/8/10, Luis Carlos <carlosf...@hotmail.com> wrote:

Hi Pgoswami,
 
There is no other material to be welded.
 
We are working over Turbine's casing and we found those damages you can see on attached pictures.
 
By metalography we know they were fabricated on A-216 WCB and A-217 WC9
 
We appreciate your comments and suggestions

Hi Shashank,
 
Thanks for attachment.
I found on it the T23 filler metal for 2.25Cr-1Mo. I will make a comparison between it and others that Pgoswami has suggested.
 
Thanks for your interest Shashank.
