in the explosive welds do not move

[Half65]

Hi.
I made a soldering (indicated with the red ball) and made it solid but at the time of exploding the components despite the selections as you see in the central image, it makes me move only the affected components while the soldering remains fixed nailed and I did not find a way to move it together with its components (or even alone) as you see to the right.
Can you help me?

explosives only command components.
You can hide the welds.
