Making my own weld beads for Solidworks Visualizer

I am trying to make custom "weld beads" so I can see them in Solidworks Visualizer. Maybe I am not thinking hard enough, but how will I make them. There will be one on each flange connecting to each pipe, and then the 2 cross ones. I have many others, but this is one example.
