dporter,
WELCOME TO THE AWS WELDING FORUM!! Glad you joined us.
As to your inquiry, I would note a couple of items:
1) Clause 3.13.4 clearly states it is "Details for CJP GROOVE welds welded from one side without backing in tubular T-, Y-, and K-connections..." This section is for TKY connections with "GROOVE" welds.
2) If your approved prints do not call out 'GROOVE' welds and list them as 'CJP' and are used in a TYK connection then this section and Fig do not apply.
3) If your approved prints call out 'FILLET' welds with no reference to 'CJP' then Clause 3.9.2 applies with Figure 3.2 and possibly 3.11 if it is a skewed T-joint.
Other sections covering fillet welds: Clause 2 Part A & D (not B which is where 2.8.3 is) 2.1-2.3, & 2.19-2.26 especially 2.2.5.2, 2.3.2, 2.3.3, & 2.23.1 would be good places to check out.
The main issue I see in your example is to rather it is a CJP Groove Weld OR a Fillet Weld. You can't use one for the other. The drawings will determine which it is and that will determine which part of the Code is to be used to complete the inspection.
Have a Great Day, Brent
