![]() Fillet, Groove, Flange, Flash, and Upset welding symbols. These symbols are used in many welding processes in congestion with welding symbols and are used as shown in figure 3-3. Figures 3-7 and 3-8 illustrate the weld-all-around and field weld symbol, and resistance spot and resistance seam welds.į. (3) When no specification, process, or other symbol, the tail may be omitted (fig. Letter designations have not been assigned to arc spot, resistance spot, arc seam, resistance seam, and projection welding since the weld symbols used are adequate. 3-5), the process may be indicated by one or more of the letter designations shown in tables 3-1 and 3-2. (2) When the use of a definite process is required (fig. (1) These welds are indicated by using a process or specification reference in the tail of the welding symbol as shown in figure 3-4. Brazing, Forge, Thermit, Induction, and Flow Weld Symbols. These basic weld symbols are summarized below and illustrated in figure 3-3.ī. Weld symbols are used to indicate the welding processes used in metal joining operations, whether the weld is localized or "all around", whether it is a shop or field weld, and the contour of welds. The locations of welding symbol elements with respect to each other are shown in figure 3-2.Ī. The assembled "welding symbol" consists of the following eight elements, or any of these elements as necessary: reference line, arrow, basic weld symbols, dimensions and other data, supplementary symbols, finish symbols, tail, and specification, process, or other reference. 3-2) is a method of representing the weld symbol on drawings. ELMENTS OF A WELDING SYMBOLĪ distinction is made between the terms "weld symbol" and "welding symbol". ![]() If notations are not used, the tail of the symbol may be omitted. The notation to be placed in the tail of the symbol indicating these data is to be establish by each user. The process, identification of filler metal that is to be used, whether or not peening or root chipping is required, and other pertinent data must be related to the welder. If a welder knows the size and type of weld, he has only part of the information necessary for making the weld. The tail of the symbol is used for designating the welding and cutting processes as well as the welding specifications, procedures, or the supplementary information to be used in making the weld. Accordingly, the terms arrow side, other side, and both sides are used herein to locate the weld with respect to the joint. Any welded joint indicated by a symbol will always have an arrow side and an other side. 3-2) is used to designate the type of weld to be made, its location, dimensions, extent, contour, and other supplementary information. The reference line of the welding symbol (fig. The joint is the basis of reference for welding symbols. This is the method predominantly used in the United States. The scheme for symbolic representation of welds on engineering drawings used in this manual is consistent with the "third angle" method of projection. Welding symbols provide the means of placing complete welding information on drawings. You can also use the Windows Character Map to select additional symbols to insert.Welding cannot take its proper place as an engineering tool unless means are provided for conveying the information from the designer to the workmen. The Symbol Library lets you select multiple symbols from all the symbols provided by the SOLIDWORKS software. Use end treatment symbols to represent the end view (section) of a weld bead on a drawing. You can manually insert representations of weld beads as end treatments or caterpillar symbols in drawing documents. The software supports ANSI, ISO, GOST, and JIS weld symbol libraries. You can use the Weld Symbol tool to add weld symbols to assemblies, drawings, vertices, and edges or faces of parts. The symbol conforms to the size of the selected hole. You can add dowel pin symbols to holes (circular edges, sketched circles, or arcs) in drawings. The SOLIDWORKS software supports the ASME Y14.5-2009 Geometric and True Position Tolerancing guidelines. The geometric tolerance symbol adds geometric tolerances to parts and drawings using feature control frames. You can attach a datum target and symbol to a model face or edge in any document. You can select the face in a part, assembly, or drawing document. You can specify the surface texture of a part face by using a surface finish symbol.
