Re: [MW:28276] how to select filler metal for a specific Material according to ASME Section IX

For welding A 517 one has to be critical about selecting a proper welding process and PHWT besides the filler metal.  Many have selected E11018 and thought they are good to go and then their PQR tests have failed dramatically. You have to find a very low heat input process with proper PHWT to successfully pass PQR tests. I used GMAW-P to accomplish this and it was successful. Yet you have to pay an welding engineering expert to supervise the whole process (including production welding after PQR).

Adeel,

 

SA517 Gr B is Q&T steel, with very high tensile strength . Selection of welding consumables matters a lot on the design conditions. Go to the web page of this group. Type in SA 517 in the search box, you'll find tons of discussions and answers.

Welding of this steel is not easy. Hence don't adopt hit and miss approach. Get a knowledgeable  welding engineer to help your organization.

 

Thanks.

Dear Experts,

 

Please answer this question 

 

For example designer selected a material SA517 Gr B for work.

 

I went to to table Q/QB 422 for P no. & G no. ... I found P no. is 11B and G no. 4. 

 

Then i went to Section ii Part A where i found SA 517 Material is alloy steel and its SFA no. is 5.5.

 

After that what shuould I do ?

 

 experts (Who has thorough of ASME Section IX) please tell me step  by step how to select exact filler material. from section ii part C.

 

I shall be very thankful to All of you for this act of kindness.
