Weld
(OP)
I appreciate your input
I have the option to locate the weld parallel to the load "P" or perpendicular to the weld, any of the choices is better or recommended from the other?
Thank you

RE: Weld
- In short, for fillet welds, parallel is superior.
RE: Weld
Thank you for your response. I have the AISC 9 Edition old book and didnt see table J-2.5
I guess is a different version. can you possibly attach that table, I would greatly appreciate it
Is it directly stating the weld parallel to load is better?
Thanks
RE: Weld
Paraphrasing for fillet welds - Tension or compression parallel to weld axis - this loading need not be consider in design of welds joining the parts.

RE: Weld
A great explanation of the condition Teguci mentions can be found in an article (Welding Wisdom Part One) by Duane K. Miller in the August 2015 issue of Modern Steel Construction magazine. The article is available here: http://msc.aisc.org/globalassets/modern-steel/arch....
RE: Weld
I will see your Duane K. Miller and raise you Omar Blodgett - Please note his interpretation regarding parallel loading. Please also note that the conclusion is that fillet welds loaded parallel are weaker. Muy mal. In this case either AISC is wrong or Omar is (and I definitely am). I do not accept Miller's interpretation because we don't design welds for non-existent loads (in his figure 1 and 2 because there is no load transfer therefore the welds are good doesn't pan out).

RE: Weld
May I ask where (what page and what paragraph) in the Duane K. Miller paper states that weld perpendicular to loading is better than parallel?
Guy, please help me to get the bottom line, I am confused now
Dont need arguees, I was simply asking for some direction
I am an EIT
Thank
RE: Weld
Regarding the articles, figure 1 and 2 of Millers article show a welded box shape with no shear transfer between elements (the welds at the corners transfer no significant load = therefore OK). Blodgett's article says transverse loading will create a lower stress on the weld than a parallel weld. AISC, states for fillet welds with tension or compression parallel to weld axis - this loading need not be consider in design of welds joining the parts.
I consider AISC as the legal authority on this while I'd consider Blodgett the preeminent expert on all things welded. I am unfamiliar with Miller, but Modern-Steel magazine is reputable. Therefore, even the experts are at an impasse with no discernible bottom line.
RE: Weld
(assuming as before, we're talking about shear through the weld throat)

Thanks for response, please reference which AISC edition and what page or what table or paragraph
Thank you so much
Any other references stating this please attach only that page or paragraph
RE: Weld
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
RE: Weld
Now the question here is when you have a beam sitting over another beam crossed (assume both are w shapes and same size) and to provide a lateral support for the below beam (which supports above beams sitting on it) by the above beams where do you locate the welds parallel to above beams or parallel to the below beam?
Please draw it so your answer is clear to be understood.
Very much appreciate it for it
I look forward for your comment

RE: Weld
As for me bringing valuable points, I feel that all I did was muddy the waters. Thanks Hokie for cleaning up.

RE: Weld
I appreciate all helps truly.
Kootk, your explanation was very clear and no needed for a sketch.
Teguci, thank you for the link, it was good information. And you I appreciate you for your discussions and that caused I learn a lot.
You guys are great.
Thank you all
