Is there such a requirement as minimum length for groove welds? 1

[Serhiy2]

Good day. I'm designing a reinforcement for the existing open web steel joists and I'm wondering if there is such a requirement as the minimum weld length for the flare-bevel groove weld? I've always used 1.5" minimum and there is such a requirement for the fillet type weld but there is nothing for flare-bevel. I looked into AWS D1.1 and CSA codes and couldn't find anything about it. Thanks

The AISC Specification Section J2.2b(c) says "The minimum length of fillet welds designed on the basis of strength shall be not less than four times the nominal weld size, or else the effective size of the weld shall not be taken to exceed one-quarter of its length."

Not 100% certain on a minimum. I know Simpson calls for 1" flare-bevel welds on some of their hangar welds so I guess it's that or less if that helps.

I'm similarly not aware of a specific requirement that would apply to flare bevel welds, but I would consider it similar enough to a fillet weld that I'd stick to J2.2b(c) as 271828 mentioned
