Area of revolution As applied to the testing of welded objects, an area of revolution specifies a multi-sided portion of a part or object to be tested. The area to be tested is indicated by the examine-all-around symbol, with or without a length dimension, depending upon the extent of the area to be examined. When […]

This unit will focus on selected fundamental symbols and terms for reading geometric dimensioning and tol­erancing (GDT) drawings. The content is limited to the extent that is required for reading foldout drawing #8, Roller Stand Weldment. Additional study will be necessary for reading more complex drawings. Geometric dimensioning and tolerancing is the most current standard […]

A computer workstation is where CAD drawings are produced. Basically, there are two main classifications of computers: mainframe and personal computers. Mainframe computers are used extensively by large corporations and governments for a variety of functions because of their speed and power. However, main­frames are extremely expensive and therefore are not effective and efficient solutions […]

Computers have increasingly become an integral part of the design and manufacturing environment. The engi­neering professional and support staff use computers extensively for the production of working and design drawings. These drawings are created using a variety of different drafting and design programs designed to produce two-dimensional and/or three-dimensional (length, width, and depth) drawings, see […]

ISO symbols for weld representations are generally found on drawings prepared with the views shown in first — angle orthographic projection. The symbol for indicating this is illustrated in Figure 26.7. Dimensioning on drawings is in the metric system, usually given in millimeters (mm). In first-angle projection, the top view is shown below the front […]

The variety of dimensions applied to ISO symbols and their locations with respect to the symbols are similar to AWS welding symbols. However, there are a number of differences, as will be found in an analysis of Table 26.3. Examples of the use of ISO symbols are illustrated in Table 26.4 through Table 26.8. For […]
