Welds going through walls and making interference

Hello,

I've been asked to add welds to our main frame assembly using the "Weld Bead" command in the assembly tree. When I add the weld beads to the assembly the welds seem to go through the walls and cause a interference issue with the part. im not sure why it does this with the "weld bead" command but if i create the assembly as a weldment and use the fillet weld command it does not to this. BUT to save us time of remodeling the whole frame we would like to do this in the assembly instead. is there a way around the beads creating a full circle bead and only creating a semi cirlce to eliminate the interference?

Below are pictures it took of the interferences i dscribed above.
