RE: ASTM

In addition to what Ben stated, you can fillet weld either the A496 or A706, but you will not be able to use the stud gun unless you use the A 496. 
 
The manufactured DBA's have the dimple and come with the appropriate ferrules.  You would have to do a bit of custom machining to use a regular A 706 bar in a stud gun.

Jason,
 
A 496 material is the correct designation for the material used by the Nelson arc welding machines.
 
A 706 material would be acceptable for use, in lieu of A 496, if the contractor intended on providing all-around fillet welds to the structural steel (be prepared to give them an appropriate weld thickness schedule, and don't forget the visual inspection).  Fillet welds work up to #6 or somewhere in there before your cross sectional area to circumference ratio makes it impossible to connect with fillet welds.
 
If you're on a small job, contractors sometimes seem to opt for welding the bars themselves rather than bringing in the specialty equipment for the DBAs.
 
A 518?  From what I see this is an iron casting designation.

Anyone know what the current ASTM designation for DBA (deformed bar anchor) is?
 
I have some shops coming in specifing A496, another set specifing A706 weldable rebar, and another set with A518. 
 
Just wonding what I should be specifing for just a general application?
