When I went through that book about 4 years ago, stud welding was covered using a "stud welding machine" working similar to a spot welder. I've never done stud welding so my memory is not very sticky in that area. I don't remember any SMAW specs on it but I may be wrong. A college book store near you will have it to peek in and some welding suppliers have the book for reference.
I did a job for Water and Power in Boulder City, Nevada, about 15 years ago. It was all red metal studs. They required me to weld it with 3/32" 6011 straight polarity. Those rods run very nicely, and it was very easy. I believe that government code would require a pretty good weld, but don't know if your job will have the same specs.
Can't give you any specific codes or information or places to look, just telling you what was required on a government job. I used the rods on lots of other stud welding jobs, and inspectors passed them. Of course, the welds were outstanding to start with................ ;-) Welding with 6011 straight polarity is easy except for vertical up. I did most all passes in vertical traveling down, and there is adequate fusion on that thin of a metal in that welding direction. Flat and horizontal was easy, too, and if you have an infinitely variable machine, you can dial it in. I was using a Miller Thunderbolt, and it did fine at those low settings.
You really need the code. I am drawing from the Canadian which is similar. In the first place you will have to use a low hydrogen process. check for required preheat if you are attaching to heavy plate. You should grind off the aluminum nub in the center since you are not going to shoot it. stud diameter ------ fillet size
6-11 5 mm
Seriously you need a copy of your code. It would be more than stupid to start without full knowledge. You are likely to be looking pretty foolish when some inspector drops the hammer on you. Bin there... done that! Randy
Aha, here's where we have our disconnect. These are shear studs. They are normally shot with a stud gun that uses the stud itself as the electrode. A shear stud looks like a strutural bolt but without threads and of course no hex head but round. Thanks anyway.
