Seal weld as strength weld?
Seal weld as strength weld?
(OP)
Connection details on our design drawings show a 3/16 fillet weld, both sides, for a 3/8" gusset plate welded to the flanges of W shapes, say W10 x 45. Gusset plates are utilized for the connections of vertical bracing, welded to beam, bolted to bracing.
Although a 3/16 fillet is all that is needed for strength, the "green book", Tbl. J2.4, states that the minimum weld in this case is 1/4 based on the flange thickness of the W10.
The detailer has followed our design drawings and called out for a 3/16 fillet weld, but also states that 1/4 seal weld will be used. Assuming that the 1/4 seal weld is actually what will be fabricated in the shop can we assume that the 1/4 fillet seal weld will meet the requirements of Section J2?

RE: Seal weld as strength weld?
My advise would be to have him call out the 1/4" fillet on each side to make sure that you are in line with the spec. If the fabricator is a stand up guy, he won't have a problem with the extra 1/16th.

The fabricator got back to me and stated that the minimum weld used is 1/4 regardless of the details provided, or the shop drawing callout.
I knew we could get it worked out, I just did not look forward to marking up 250+/- shop drawings.
The client is not located within the US, and has not upgraded his specifications beyond the green book.
Thank you again.
