W10x15 Reinf.

[XR250]

Need to double the Ix on this W10x15.
Do y'all think i can get a fillet weld in there or should I maybe try plug welds?
Any better ideas?

No chance on a good fillet. What are you constraints around the beam? I'm guessing a plate on the bottom flange and angles (one toe fillet welded to the bottom of the flange, the other to the web to make a pair of boxes) is a no go?

 

[XR250]

I have don't have too many constraints. Are you talking about reinf. the bottom flange only or are the angles on the top flange?

 

[kipfoot]

You get pretty close with back to back MC6X18s, and a little more room to get an electrode in there.

Honestly, I could thru bolt this. A mag drill would make short work of it and it would be safer than welding inside of a house.

 

[phamENG]

angles for the top flange (assuming something is sitting on it), plate for the bottom flange. Doubling the I_x may be a big ask of that, though.

 

[XR250]

Good point, kipfoot

 

[XR250]

Just sent it to 2 steel fab friends of mine. One said he could get a decent weld. The other said drill it and thru bolt.
I agree that getting a decent weld would be challenging, but to be fair, the demand ain't too high

Ahh, got it - thanks.

I don't see why you couldn't make this weld.

With everything on the same CL (no shear flow), I'd lean towards bolting if there's no extenuating circumstances.

 

[KootK]

I like bolting if there's no resistance to that.

You could also double Ix with 1" diameter rods and pretty conventional welding.

 

[XR250]

I like that detail. Just talked to the contractor. Thinks bolting would be preferred. Thanks for all the help.

I would try the channels located at the top and bottom flange of the W section . Typical compound beam sections picture from (Steel Structures Design and Practice by Narayanan )
