The fillet weld will connect the plate to the web of the W shape. That connection in the analysis model is already established by the fact that your beam and plate is sharing a common node. If you are interested in finding out the force in the weld, you can find that out from the element joint force and the beam shears at that node.
Now couple of unrelated observations :
You applied a concentrated load beyond the full length of the members 63 & 64. The software will apply the load at the end of these members which are 3.84 ft long.
A SELECT OPTIMIZED command should be followed up by PERFORM ANALYSIS and CHECK CODE commands.
