Welcome to the forum Dell!
This may be over simplified,
ANSI/AWS A2.4:2012 Standard Symbols for Welding, Brazing, Nondestructive Examination provides a system of symbols that represent the significance of weld profiles with the ability to make notation of process used in order to achieve any specific profile.
As a process engineer, I assume you have an appreciation of the "process control" value of requiring specific weld contours in sheet metal, and having these things in mind during the planning stages, long before production begins.
Grinding becomes less of a factor when weld profiles are clearly set forth in the production drawings.
Putting more emphisis on profile (to the welders) rather than on grinding after welding, may accomplish greater dividends for you. Not to say grinding processes and controls aren't important and don't need to be clearly communicated. But rather that there will be much less of it if the welding process itself gets first and formost attention.
Clearly stated weld profiles
* Reduce grinding operations significantly from the outset.
** Reduce oversized welds which in turn
***Reduce arc-on time
****Reduce Distortion
*****Reduce rework time overall
******Increase quality, production rates, profit
