Welding symbols on drawings - .:YUSUF MANSUROGLU - P

terms and <strong>symbols</strong> should be avoided. A root dimension can be
specified whatever its thickness and there is no point in having a
special definition ‘broad root face’ when the root face is greater than
2 mm.
As stated previously, when ISO 2553 is used, the dimensions of
the edge preparations are not included as part of the welding symbol
and should be given as part of the WPS. With the AWS system, the
depth of the groove can be specified by a number on the left hand
side of the weld symbol. This dimension, subtracted from the
section thickness, will indicate the size of the root face (Fig. 3.2).
