Welding Symbols and Codes 231

Welding Symbols and Codes describes how welding prints represent welding requirements. A weld is represented in a print using a welding symbol. A welding symbol includes a reference line, arrow element, weld symbol or symbols, and weld dimensions. A welding symbol may also have supplementary symbols and/or a tail when needed to indicate additional information. The American Welding Society developed the welding symbol to indicate different weld requirements. Many of the requirements for a weld depend on which welding code is being used. The various components of a welding symbol indicate the characteristics of the weld and provide specific instructions to the welder. After taking this class, users will be able to describe the requirements for a weld based on the different parts of its welding symbol.
