Groove welds between "thin" steel
Groove welds between "thin" steel
(OP)
I recently specified a C6x8.2 channel to have a moment connection to another C6x8.2 (as a backspan member for a cantilever). I specified a CJP weld at each flange. My senior engineer said he doesn't trust groove welds of any kind on material less than 1/2" thick (C6x8.2 has a tf = 0.343); due to experience observing welders burning through the steel. Is there some merit to what he is saying? I can imagine it happening, but I am reluctant to re-configure my framing for this reason alone. My logic is that what is stopping a bad welder from burning through "thinner" material when it is a fillet, plug, etc.? We specify sheet metal welding and fillet welds on thinner structural steel all the time without a care. I don't understand his logic, but maybe someone can convince me otherwise.

No.

If the connections are subject to static loads, PJP groove welds are acceptable. An alternative is the fillet weld the members to plates connections.

The irritation for me with the CJP welds I specified, was that I had to reconfigure the stability of the frame since those CJP welds were critical in my initial framing layout. And the re-configuring resulted in more work for me and the installer. Oh well. Thank you for the comments.
