Welded Headed Studs
Welded Headed Studs
(OP)
If a contractor decides to fillet weld headed studs to abeam instead of using a stud gun, is that equivalent in strength. I know this depends upon the fillet weld size but I thought I remember hearing something in the past that told me they are not equivalent. I cannot seem to find my reference right now. Can someone help me out?

A fat doughnut fillet weld seems as strong or stronger than a stud gun's weld to me.

The headed studs typically have a small setoff on the bottom. Does this need to be ground off before fillet welding?

Weld size should be in accordance with AWS as mentioned in one of the other posts.

They can be attached by the typical arc process or with capacitor discharge. They can also be fillet welded. Stuck is stuck as long as you test it like JAE said.
Since studs are mild steel, the welding process (either of them) doesn't screw up the metallurgy.

Say if for some reason they used a smaller fillet for all the studs than what AWS specifies but the test still worked. Would that also be acceptable? Is the intent that if the 10% tested works, that this can be extrapolated to 100% of the studs working on the whole project, or is there some accepted failure number based on the test PLUS the rest of the AWS criteria?
