In the railings and metals world, NOMMA is the National Ornamental and Miscellaneous Metals Associations based in GA.

Something that may interest you and that you may have already in some specs are the 4 Joint Finish Categories they have produced:
Joint 1 No evidence of welded joint
Joint 2 Completely sanded joint, some undercutting and pinholes Ok
Joint 3 Partially dressed weld with spatter removed
Joint 4 Good quality, uniform undressed weld with minimal spatter

Needless to say, Joint 1 specifies the best quality weld. For more information, visit NOMMA's website.
