Dear Krishna & Others,
As everybody said correctly, consumable certificate may not have the details other than Chemical analysis. But that does not mean that it is acceptable.
It all depend what you specified (either your client requirement - informed to supplier or requirement specified in Purchase order while ordering) in your PO.
ASME Sec II C SFA 5.01 specify in clause 6.2 Schedule F : The level of testing shall be the manufacturer's standard. The statement, "The product supplied shall meet the requirements of the applicable AWS fillermetal specification, when tested in accordance with that specification" and a summary of the typical properties..
it means if you have not asked anything the standard certificate with earlier tested values can be provided (it could not be actual chemical analysis even). So please go through the Sec II C SFA5.01 thoroughly and see that you are meeting all your client requirement. You must specify the Lot classification and batch certificate shall be verified accordingly.
To get the correct properties of the production weld (in case where production test coupons are required with simulation or actual heat treated condition) it becomes very important to have batch certificate of Flux with all the testing specified in AWS classification (such as SFA 5.17 for Carbon steel wires / flux).
Regards.

I too agree; SAW filler wire may not be tested for Mech properties as
the properties are purely based on the flux combination. if the client
is very particular about the mech properites, an all weld test piece
can be tested at lab for mech properties as per spec.
Thanks
