我在看2019版的asmeIX，你说的这个引用在标准哪里有提到吗？？

ASME  IX 2017的QW462 中有明确的引用标准，2019版虽然没有明确标准，但是可以使用替代标准。

Figure QW-461.10
Rotating Tool Design Characteristics (FSW) Referenced in QW-410
QW-462 TEST SPECIMENS
The purpose of the QW-462 figures is to give the organization guidance in dimensioning test specimens for
tests required for procedure and performance qualifications. Unless a minimum, maximum, or tolerance is given
in the figures (or as QW-150, QW-160, or QW-180 requires), the dimensions are to be considered approximate. All welding processes and filler material to be
qualified must be included in the test specimen.
The following nomenclature is in reference to Figures
QW-462.1(a) through QW-462.1(e): T = coupon thickness excluding reinforcement
W = specimen width, 3/4 in. (19 mm)
x = coupon thickness including reinforcement
y = specimen thickness
As an alternative, any tension specimen dimensional
geometry meeting the requirements of another welding
qualification standard is acceptable as long as a cross section can be measured so that an ultimate tensile strength
can be determined. All welding processes, filler materials,
and heat-affected zones to be qualified shall be included
in the test specimen. Weld reinforcement shall be removed prior to testing
