HSS to HSS weld 1

[WARose]

I am welding the end of a HSS 4x4 to the wall of a HSS 6x6. I am just welding on the flats on two sides (with a fillet weld). I was thinking the best way to communicate that is to say (at the tail of the weld symbol) "on the flats". Do you agree? Is there maybe a better way to put it?

 

[Ron]

How about a weld symbol that shows a fillet all around?

 

[WARose]

That won't work. The useable flat dimension of the HSS 6x6 is less than 4".

WARose:
Why not show a simple, but to scale, section through the joint? Show dimension lines on the two flats, with 3 or 3.25," or whatever, and a note pointing to both, ‘.25 fillet weld by 3" long both places.' Your dimension lines cover only the flats of the 4x4, if I understand you right.

I thought about putting the weld length on there......but I thought just mentioning in the note part that it is on the flats would be sufficient. (But didn't know how to exactly state it.)

It's generally done with a fillet weld on each side of the flat part and a flare bevel weld on the opposite sides... but I often see it spec'd on engineering drawings and the occasional shop drawing as a fillet weld all around...

On a 6x6 if the 4x4 is welded, you can use a fillet weld all around... sorry Ron. Just show the symbol pointing to the two sides you want welded.

I don't see how. A HSS 6x6x1/2 has a useable flat of 3.75". It can't be all around as a fillet.

 

[KootK]

I like "on the flats" and cannot think of anything better short of trying to stuff a paragraph behind the tail. "Weld only where tubes are in direct contact" seems a bit much.

You could spec a 3.75" weld length and hope the detailer "gets it".

 

[WARose]

Thanks Kootk.

 

[Tomfh]

Why does it have to be the flats, as opposed to the sides?

 

[dik]

If that's the useable flat then you spec a fillet and flare bevel... and let the welding symbols denote the sides... and I generally put the weld thickness for flare bevel welds in brackets to denote effective thickness.

From AISC database for HSS 6x6x3/8, the flat is 4.3125 approx... and I'd call it a fillet weld.

Not my size...I have a 6x6x1/2. But what Kootk said is what I need.

Thanks...

I don't see why you can't weld all around as Ron said. Filling a tiny gap is not a problem. Surely you don't want to leave it open.
