Unless you are doing something wrong then your joints should not break. I'd be more concerned with my knot untying or messing up the movement of the ball/rollers.
The way we have done polycord welding was with a heat gun (or flame but you have to keep the cords in a magic spot so they don't burn and so that they aren't too far away, heat gun preferred). Once you see the two cords turn liquidy on the end we pushed them together and held them for a minute or two until they cooled. Once they have set for a while we would take a knife and shave off the loose ends. We did this in 2009 and I can't remember a single joint breaking it is wicked simple and so easy I don't know why you would consider tying them.
Take a small segment and trying melting them together as a test before resorting to tying. A little too sketchy with polycord for me and I have never seen that done before.
