<Mesh Tools><Remove Doubles> works if the proximity is set accordingly high.
It does not remove the join and make the object into one piece.
Take 2 cubes joined and close together, so 4 verts of each are in proximity say 
0.2 blender unit apart.
Rem Doubles works if the Limit (proximity)  is 0.21 or slightly larger than the 
distance between.
I guess this would work for any distance up to the maximim of the Limitprovided 
the Limit is suitably set.

Its all extra work when simple selection of verts and merge would speed the process.
