The final stages of fabrication
There are two key stages following welding:
It is often desirable to grind or 'push' back a weld after welding is complete. This allows for a cleaner finish, a more even surface, and better component tolerances.
The final stage of fabrication is to apply finishes. Finishes are surface applications which serve multiple functions, including to protect from oxidisation, to protect from damage, and to give desired aesthetic outcomes.
