DIMENSIONS APPLIED TO ISO SYMBOLS
12 ноября, 2014 
Oleg Maloletnikov 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 purposes of clarity, dimensions have not been applied to these symbols.
A comparison of ISO symbols to AWS welding symbols is found in Table 26.9. Additional symbols applicable to AWS and not found in ISO symbology are illustrated in Table 26.10.
Examples of Use of Symbols
Table 26.4 through Table 26.8 give selected examples of the use of ISO symbols. They are given for explanation purposes only.
