Gentleman,

  After spending countless hours and pulling my hair out, please someone opine via code backed data regarding the following; AWS D1.1'06, TYK PJP's as per Figure 3.5
Knowing that "root face" is an essential variable as per Table 4.5, I am of the opinion that the "root face" is not applicabe regarding Figure 3.5, thus electing "n/a" on the Welding Procedure Specification is correct. Is this correct or should "0" (zero) be placed? Am I splitting hair here?

Thank you
