What group material?

What group material?

What group material?

(OP)
as using AWS D1.1 for choosing material group but i don't know ASTM A709 Gr.70 and API 5L X65 material belong to what group. can someone give me a advice?  

RE: What group material?

ASTM a709 is a group IV material.  I didn't see API 5L 65 stated as such, but A572 and A913 have grade 65 materials with similar yield/tensile requirements as APL 5L X65

RE: What group material?

Details...572/ are Group III materials

RE: What group material?

If advice is what you seek please see AWS D1.1 table 3.1.

I don't see API 5L X65 in the table.

Is this one of the fictitious base metals used only in Part B practical of the CWI exam?

I took the CWI exam this past Saturday and I seem to remember seeing these two metals in a couple of questions.  The questions concerned correct electrode selection when joining these two base metals.  I think the question was something like:

On the third Friday of October during a leap year of an odd numbered decade when the autumn moon is full and the catfish were jumping on the previous Tuesday and when using FCAW on the root pass and SMAW on the remaining passes of a CJP groove weld what is the correct filler material classification if joining ASTM A709 Gr.70 and API 5L X65?

That's not the question verbatim but just imagine a question cryptically greater than or equal to that and you have the idea.
