7.16 SECTION SEVEN<br />

FIGURE 7.5 Symbols for shop <strong>and</strong> field welds.<br />

in final position. This is the responsibility of the fabricator’s engineering staff <strong>and</strong><br />

is discharged during the making of shop drawings. However, the basic design configuration<br />

must permit the necessary clearances to be developed.<br />

Clearances are required for two reasons: to permit entry, as in the case of bolts<br />

entering holes, <strong>and</strong> to provide access to the connected elements either to allow the<br />

tightening of bolts with field tools or to permit the movement of manual electrodes<br />

or semiautomatic welding tools in depositing weld metal.<br />
