WPS includes double bevel joints.
Also here is ASME Interpretation that has not been superceded;
Interpretation: IX-83-90
Subject: Section IX, QW-452.1
Date Issued: November 21, 1983
File: BC83-407
Question (1): Can a double-beveled plate, 1 in. thick with each beveled groove being of 1/2 in.,
be welded by a welder qualified to weld a weld metal deposit of 0.864 in.?
Reply (1 ) : No.
Question (2): Can the same joint as above be welded by two individual welders, each with a
deposited weld metal qualification of 0.864 in., provided each welder does not exceed 0.864 in.?
Reply (2): Yes.
Actually Marshall, a double V groove joint is not required to be addressed in the WPS as the second welder is merely performing a single V groove weld with backing. The welder originally qualified with a 1/2" thk single V groove open butt plate in 2G, 3G, & 4G positions.
On my QW-482 forms, Joints (QW-402), I usually state Single V, Double V, Square Butt, etc for joint design and also include a statement in the notes; "In addition, joints having groove designs resulting from end preparations conforming with ASME/ANSI B16.25 and prequalified joint details from complete joint penetration groove welded joint permitted by ANSI/ASE D1.1 are also allowable for application with this WPS.
I figure if ASME Section IX can reference AWS Standard Welding Procedure Specifications in Article V and Appendix E, I can reference AWS joint designs.
Besides, it has held up under scrutiny of ASME & NBIC review/audits for our "U", "PP" and "R" stamp certifications.
PS,, anyone who has met me would tell you that I am not the type to usurp anyone's authority. I try my best to come across congenially with the attitude of how can we resolve this matter that most benefits the job in a timely and safe manner. Unfortunately, this particular inspector was not of such frame of mind or attitude.
