1. Basic Symbols 1.1 Distinction Between Weld Symbol and Welding Symbol. This standard makes a distinction between the terms weld symbol and welding symbol. The weld symbol indicates the type of weld and, when used, is a part of the welding symbol. 1.2 Weld Symbols. Weld symbols shall be as shown in Figure 1. The symbols shall be drawn "on" the reference line (for illustrative purposes shown dashed). 1.3 Welding Symbols. The welding symbol consists of several elements (see Figure 2). Only the reference line and arrow are required elements. Additional elements may be included to convey specific welding information. Alternatively, welding information may be conveyed by other means such as by drawing notes or details, specifications, standards, codes, or other drawings which eliminates the need to include the corresponding elements in the welding symbol. All elements, when used, shall have specific locations within the welding symbol as shown in Figure 2. Mandatory requirements regarding each element in a welding symbol refer to the location of the element and should not be interpreted as a necessity to include the element in every welding symbol. 1.4 Supplementary Symbols. Supplementary symbols to be used in connection with welding symbols shall be as shown in Figure 3. 1.5 Placement of Welding Symbol. The arrow of the welding symbol shall point to a line on the drawing which conclusively identifies the proposed joint. It is recommended that the arrow point to a solid line (object line, visible line); however, the arrow may point to a dashed line (invisible, hidden line). 1.6 Illustrations. Examples given, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles. They are not intended to represent design practices, or to replace code or specification requirements..
