AISC Table 8-2 (TUBE) & Table 10-13
AISC Table 8-2 (TUBE) & Table 10-13
(OP)
I am reviewing shop drawings for shear tabs welded to 6" and 8" SCH40 pipe columns. In the past, I have noticed that detailers often miss providing larger fillet welds (or switching to PJP welds) to make up for the acute angle on skewed shear tabs. The questions are:
1. Does Table 8-2 for tubes apply to shear tabs welded to round HSS/pipe? If so, am I correct that you must always use PJP welds for this condition?
2. Or - can you still use fillet welds and verify with Table 10-13 by increasing the skew base on the additional angle between the end of the fillet leg and pipe/HSS wall?
Sketch attached.
Thanks a bunch!
p.s. - the attached sketch certainly doesn't have the worst case shown.

Hope that helps.

Maybe I didn't explain myself well enough. I understand table 8.2 doesn't include the prequalified details for skewed t joints - the title of the table is what I am wondering about (whether it categorically disallows fillet welds for a shear tab on pipe/round tube)
As you mentioned the AWS classifies the more dramatic angles as "Skewed T joints", which may not use fillet welds - thus, you are using partial joint penetration welds, as qualified for the application. Again, table 8-2 on page 8-63 of the AISC 13th seems to indicate their are not any qualified fillet welds for connecting to the face of pipe/round tube.
Thanks!
