If you are using SMAW, then that is not the case.
If the welder is already qualified with carbon, just do a test with backing for the SMAW if you have backing rings available.
In addition, you can machine grooves into pipe and use the welding of that groove for the performance test. This is allowed by code.

Hi All
I am trying to find the correct paragraph to calculate the minimum base metal thickness for OFW as well as ESW in Section IX of the code book. Could anyone point me in the correct direction.
