Welding Symbols and Definitions

The finish symbol reveals how to finish a weld. For example the following letters are used to convey this information on a symbol: C = chipping; M = Machining; G = Grinding; For example there is a G, as shown below, so the welder needs to grind the weld to create the contour that is needed, and the actual contour is to be 'flush'.

Surface Finish

Surface roughness, also called surface texture or finish, is a trait of any surface. The design engineer usually specifies the required surface roughness of a flange sealing surface to ensure proper function of the flange in the joint. Surface roughness is usually specified with a “check mark” symbol on a drawing as shown in the figure below.

Surface finish Wikipedia

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.
