to be used when welding the bracket to the ship’s structure & meaning of dummy bolt

Hello everybody!

The lower locking bolt bracket is secured to the locking eye of the rudder trunk by the dummy bolt, to be used when welding the bracket to the ship’s structure. (Drw.104152).

The above-mentioned sentence is about installing a thruster on a ship. I am not much of an expert on these things, hence I am asking your advice.

Does "to be used when welding the bracket to the ship’s structure" refer to the mentioned dummy bolt?

What is the meaning of a dummy bolt generally?

Thank you.

A dummy part is not a functioning or final part. In this case, the bolt is used to hold the part in place while it is being welded. The bolt is not designed to stay in place or to hold the part under the normal load and conditions of its use.
