Welding a dowel/pin to a wide flange

[ztengguy]

What symbol would you use to show a dowel being welded to a flange of a beam? I am showing a fillet weld with the all around symbol, not sure thats correct.

Also, for the weld strength, what calc would you use? Just take the length of the weld? its a shear load on it.

Thanks

Why not use a coupler to the beam? Is the dowel weldable? For a coupler the weld is made to achieve 125% of the yield strength of the bar, or some variation, which is generally a flare bevel-fillet combo weld. I guess otherwise I would use the length of weld as you described, but I use couplers in this situation.

Do you mean a rebar (weldable rebar) dowel, like 90 deg to the steel material? Yes, you would use an all-around fillet weld.

Agree...fillet all around. Shear calc is length of weld taken at center of the throat.

You could specify a "Nelson" stud...a resistance welded stud if you have multiple ones to do.

If we're talking about welding rebar to a steel member, a fillet weld full perimeter won't come anywhere close to developing the bar. As structSU10 indicated, a flare bevel fillet weld combo is more appropriate.

You could also look at another Nelson product, the Deformed Bar Anchors (DBA)

Its to resist about a 1K lateral load from a precast panel. It would be weldable rebar dowel, then grouted into a hole into the panel. Friction of the panel weight would hold it in position, this just a mechanical way to fasten.

Anyway, thanks, will specify a fillet weld.
