What is the symbol for a flat contour in welding?

The symbol for a flat contour in welding is a straight line. This representation is used because a flat contour indicates that the surface is even and level, with no significant curvature or deviation. In welding print reading, outlines or edges that are meant to be flat are denoted by this straight line symbol, making it easy for welders to understand the required specifications of the components they are working on.

A straight line effectively communicates that the welder should maintain a uniform surface, which is critical for the integrity and fit of welded components. Recognizing this symbol aids in ensuring accurate interpretations of design specifications, which is crucial for successful welding operations.
