Hello Tom;
Is anyone watching your operation?
Get it done before someone catches you! If the inspector is bird dogging you, buy him a coffee and give the sports page and git it done while he's busy reading.
Let's get serious. You have a WPS that was qualified by testing. The PQR records the groove angle that is greater that what is typically used by a prequalified WPS, but wait, Table 4.5 says you are still qualified to weld and prequalified joint detail per clauses 3.12 and 3.13 which leads you to the joint details shown in figures 3.3 and 3.4. (Reference D1.1: 2010, Table 4.6, item 31)
Check your base metal. You listed ASTM A710, but you didn't list the grade. That may makes a difference in the range of base metals you can weld if you are not welding a prequalified base metal listed in Table 3.1 (in other words A710 Grade A class 1 or 3 as found in Table 4.9).
I may be missing something, but hey, the advice is worth every penny you paid.
Best regards - Al
Hi Al and thanks for your valued opinion.
The alloy used during the original PQR testing was A710 Class A grade 1, listed in Table 4.9, the same as will be used in the upcoming production.
If you think the original weld procedure configured with a wide 75 degree bevel ( needed at the time to address restricted accessibilty problems, or so I am told) is permitted for use on the 45 degree bevel groove joints, than what is the intent of Table 4.9 essential element #33, i.e., decrease in groove angle beyond the tolerance cited in clause 3.13 ??
