Welding Symbols

Welding symbols are used on engineering drawings to communicate the types of welds the welder must create as determined by engineering, the designer or draftsperson. Understanding welding symbols on drawings is essential for any person involved in metal fabrication and design where sheet metal or structural steel welding is required.

The key to understanding weld symbols is to look at the graphical part of the symbol as a representation of the shape of the desired weld. All of the standard welding symbols use a shape to help explain the desired outcome.
