stitched fillet weld
stitched fillet weld
(OP)
I'm used to using fillet stitch weld of floor plates to the beams 1" long every 12". One of these things that this is how we do it in the company, and no one ever questioned it.
Recently I noticed section in AWS 2.3.2.4 calling for minimum 1-1/2" for intermittent fillet welds.
Does anyone know why min 1-1/2" is required if for structural purpose 1" is enough?
Also, why the same minimum length doesn't apply to grove weld? Some of my plate will be welded to HSS, so I wanted to use stitch flare bevel grove weld also 1" every 12".
Any thoughts on that would be appreciated?

What about the grove weld? Why niminum 1-1/2" is not required?
RE: stitched fillet weld
While D1.1 uses intermittent fillet welds with segment lengths of 1 1/2 inches as a minimum length, the Farm Code has no such restrictions on the length, size, or spacing of stitch welds, tack welds, or any other weld for that matter.
As one might suspect, the Farm Code was developed to meet the needs of farmers, both large and small, that have no need to fix it right the first time. The Farm Code follows the principle of "make it stick until we get a chance to fix it again. Next time we'll put more weld on it." If that philosophy works for you and your application, the Farm Code is your baby.

Follow the standard unless you want to be responsible for your design possibly failing when you don't follow the standard.
I'm sure the PE who approved the sky walks in the Hyatt Regency in Kansas City, MO wish he would have kept his eye on following design standards.
RE: stitched fillet weld
I didn't say that I will not follow the standard. Engineering is continued learning process, and I just learned something new that I overlooked, because experienced PE was doing that way for years.
Question is why? And why does it apply to fillet weld but not grove weld?

"There is always the Farm Code 2002 for those that have an aversion to following AWS D1.1 or other consensus codes.

How about I will just use Alaskan way of connecting things together:
"duck tape" :)

Sorry if I offended anyone. It just seemed like an opportune time for the Farm Code to rear its ugly head. It seemed appropriate.
As one of the founding authors, it is about time to revise and update the FC once again. It has been several years since we all met for a couple of beers and some hijinks.
