Connections issue

Hello all,

I am having trouble with this beam/truss weldment.  The truss is supposed to be solidly connected (welded) to the top of this beam.  I cannot figure out how to get the simulation to acknowledge that.  I know it is a fundemental function of Simulation, but I have just started working in this program.  I watched the tutorials and am still still struggling with it.  If someone gave me a little direction, I could probably figure it out from there.  I have attached the files for the problem.

Thanks in advance,

Dave
