Weld symbol type? Grinding Flush?

[braves25]

Hello all,
Please see attached sketch. I am needing to weld a HSS4x4x5/16 beam to a HSS4x4x5/16 column.
The arch is wanting a flush weld. So that I actually have some "throat" thickness left after grinding, I was going to bevel the ends of the HSS beams so that when everything is ground flush, there would be throat thickness remaining.

Does this seem acceptable?

If so, with the rounded corner of the column and the bevel end of the beam, what would be the appropriate weld symbol (including the grind flat symbol)?

This weld would be all around as well, so the top and bottom of the beam would have the bevel but would be connecting to the flat face of the HSS column.

Thank you for any help/suggestions.

Your sides with the radius edge of the column are going to be what they always are - a flare bevel groove weld.

The sides that intersect the flat of the column can either be a single bevel groove weld or a nicely cleaned up fillet weld. If the architect is adamant about not being able to see the weld at all, then the groove weld accomplished by grinding is probably the best bet.

I'd recommend looking into the requirements for Architecturally Exposed Structural Steel and reviewing them with the architect to determine the level they want to achieve.

Flare bevel weld seems suitable.

near side and far side. Add a flush grind symbol to those. It cannot be all-around as the type of weld configuration changes. There isn't a need to bevel the edges of the horizontal parts if there is a radius on the vertical column.

Here's a closer example, sans grinding:

You can add field weld notes to indicate the order the welds should be in.

Grab a copy of Blodgett's Design of Welded structures from the Lincoln Arc Welding Institute - it's about $30 or so.

I think you shall combine the groove, or bevel weld symbol with a horizontal bar, and a letter "G" indicating grinding smooth. (See cases 3 & 6 below)

Stupid architect.
