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 - technetics

Surface roughness, also called surface texture or finish, is a trait of any surface. The design engi-neer 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.

AND TOLERANCING - synthetica.eng.uci.edu

Roughness and waviness require separate specifications. In addition to these requirements the designer also needs to specify the material to be used and the special conditions relating to the material. Thus complex engineering drawings and models may require you to understand several different conventions, each controlling different aspects
