ASME-Section-2C-SFA 5.23 - Spec for Low Alloy electrodes and Fluxes for SAW-Two run classification

[Zacharias Rohith Joseph]

Hello Everyone, 

In SFA 5.23, in the electrode classification, there is a character "T", which is defined as a designator for two run electrodes. 

What does this signify and how is this different in operation from the normal SAW electrodes.

Dear Zacharias,

This is an example of a Two-run test sample

This is an example of an All-weld metal test sample

And this is an example of a Multi-run test sample

Hello,

T - means Tubular and not Two runs.

Dear Mr Sandeep Mehta, 

i think you are mistaken. Pls refer to SFA 5.23. There it is clearly stated two run. 

Also i dont think there are tubular electrodes for SAW.

Tubular are for FCAW in which the flux is stored in the core, thus requiring the electrode to be tubular.
