How to model union between parts in solidworks simulation?

I have an assembly, and the parts that form it are supposed to be welded. In the past I have used rigid unions and the results came out fine. In this case, the parts are not sticking together.
I'm uploading the model and a couple of screenshots.
Any help will be appreciated.

You can define an edge weld in solidworks simulation. Right click on connections in the design tree when in solidworks simulation and select edge weld. Define your edge weld here and solidworks will model it in simulation as joint parts.
