Re: HAS Weld Symbol

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It has been my experience that small shops fabricating small projects will opt
for fillet welding of studs rather than making the investment in a stud welding
machine. It has also been my experience that they will not grind off the nipple.


Quoting "Joseph R. Grill" <jrgrill(--nospam--at)>:

> I was skimming through "Detailing for Steel Construction" second edition
> (AISC, NSD) book today.  On page 4-34 under "Stud Welds" there is a word
> description for the weld symbol for welding studs by a stud-welding gun.  It
> says a circle containing an "X" lying only on the arrow side with the stud
> size located to the left of the circle, pitch to the right and the number of
> studs in parentheses below the circle.  I have the stud size figured out,
> the pitch is the spacing?  But why list the number of studs, or for that
