I neglected to add, my Blodgett’s cost me 6 bucks brand new………a long, long time ago.

Dave's comment is good.  What he might of meant was that more weld passes would be required.  We weren't interested in a particular job but the overall economy of any project where welds larger than really required will increase the costs.  

It might be of value to read  Section 7.5 in Blodgett's "Design of Welded Structures", one of  the structural engineers bibles.

Dave –
Yep, that was me.
I understand your point about the difference in the quantity of weld metal deposed. I’m not a welder, and I’m not sure the deposition rate is the same.
The bottom line: The welder on this job says this about the proposed change: “No Biggie”.

Subject: 5/16 Fillet Weld
I think it was Bill Allen who posted a message this morning (I deleted it already) regarding changing a fillet weld size from 3/16 to 5/16 because it only amounted to a little more electrode.
In fact, a 5/16 fillet requires approximately 3 times the electrode as a 3/16 weld.
One could assume that if the deposition rate in pounds per hour were the same for both welds then the larger weld would take 3 times as long, a substantial labor cost.
