LOCATION OF THE WELDING SYMBOL ON ORTHOGRAPHIC VIEWS

The welding symbol can be placed on any of the orthographic views, but is generally shown on the view that best illustrates the joint. The location of the welding symbol on each view is illustrated in Figure 10.29. However, when the symbol is shown on one view, it is not necessary to include it on any of the other views. In Figure 10.29, note that the front view gives the best indi­cation of the joint; therefore, the symbol should be added to this view.

DUPLICATE WELDS

To save drafting time and to reduce drafting costs, it is common practice to designate sim­ilar welds by additional (multiple) arrows, Figure 10.30(a), or by an indication placed in the tail of the symbol, Figure 10.30(b). It should be noted, however, that any indication such as “4 places” must refer to obvious welds. If there is any doubt where these “4 places” are on the print, separate symbols for each weld should be applied. Note that the abbreviation “TYP” for typical may be used to indicate a repetition of identical welds and is shown in the tail of the welding symbol.
