That's a no-no in any case. The neutral is a conductor. You would not want a conductor from the AC service to be electrically connected to a steel welding table.

Bonding a welding table to the building ground system is OK to do. If your table is bonded, then you should leave the ground from your 120V receptacles isolated. This prevents any possibility of a "dual" ground path.
