    Steel balls touching each other would cold weld themselves into a clump if all touching like that. They’re going to need a couple design changes.

      Not if they’re made on earth and exposed to the atmosphere.

      The layer of iron oxide on the outside will prevent cold welding.

      Or just coat them all in grease.

        All the vibration from them rubbing against each other as they achieve orbit will rub off the Oxide layer. A light oil would probably do just fine.
