Intermittent Groove Welds
Intermittent Groove Welds
(OP)
Are intermittent groove welds prohibited by the code? If they are not, what is the minimum length that can be considered effective?
AISC and AWS are awfully silent on this issue

I was also wondering about this. I have the 1990 version of AWS D1.1, and it says in section 9.12.3:
Intermittent groove welds are prohibited.
Chapter 9 deals with Dynamically Loaded Structures. The commentary says that these welds, along with others prohibited by 9.12, do not perform well under cyclic loading. It goes on to say that "the prohibitions do not apply to welds in those secondary members which are not subject to cyclic stresses."
So, they're prohibited in dynamically loaded structures, except for secondary members with no cyclic loading, where they would be permitted. Presumably they're permitted for any member in a statically loaded structure. As far as minimum lengths, I suppose you're on your own.

I mean, you still need to build up the thickness of a groove like you would a fillet, unless you're required to use some other means such as a "side backing"?

"the effecitve groove weld length is the length of the groove weld"
