Welding Tube Steel
Welding Tube Steel
(OP)
I am checking a welded tube steel connection with TS 6x6 vertical verendial truss members and TS 6x6 chords. They are using a fillet weld all around and are counting all four sides as effective. I have heard that some codes do not allow the full perimeter (i.e only 2 sides effective) due to the radii of the tube steel corners. Anyone know if this is true and which code says this (AWS possibly?)
Thanks,
Craig

The effective weld area in plan view looks like this:
__________

<-- sides with rounded edge (not effective)

You may want to research the requirements (effective weld size of flare-bevel grooves) in AWS D1.1:2002, 2.3.1.4 and Table 2.1 if you have a structural application and the thickness of your tubing is 1/8" or greater.

The design guides give the ultimate strength of the joint. From this you can back-calculate the stress in the side walls, and so calculate the fillet weld size.
