Dear,
Leak path dimension is not mentioned in ASME section IX.
As per ASME Section IX, QW-193.1.3 Acceptance Criteria — Macro- Examination.
Using a minimum of 10X magnification, the exposed cross sections of the weld shall confirm
(a) minimum leak path dimension required by the design
On polishing & etching the section, the minimum throat thickness or leak path of each weld shall not be less than 0.7t, where t is the nominal wall thickness of the tube.
Regards
