animation of assembly of parts moving one by one into place?

Good morning all,

I had a meeting with the shop foreman this morning regarding the possibility of making some sort of assembly animation that would show the shop guys the order of how to fit/weld plates together to make a weldment.  I have several plates that comprise a box with internal smaller pieces.  I'm not familiar with animation but can read up on the process if what I'm trying to do is even possible.  Basically looking to show each part visually move into place on the weldment as an animation (.avi) before the next piece would fit to that existing assembly and so on until the assembly/weldment is complete.  Thanks in advance!
