是图上所测值，合格指标ASME上只说不低于最小泄漏通道，但最小泄漏通道值标准和设计并没有给出。在ASME int ...

再找出处呢，贴出来看看啊

参照15614-8中的画圆方式，但是并不是ASME的全部意思，只能参照

不会贴图，咋办

大致是这个样子的。参见ASME IX： QW-193 管子与管板的试验, QG-109 throat的定义；最好在看看AWS A3.0有关 ...

新版AWS A3.0-2020关于角缝Throat图示
简便明了
QG109：
throat, actual (of fillet): the shortest distance from the
root of a fillet weld to its face.
throat, effective (of fillet): the minimum distance from the
fillet face, minus any convexity, to the weld root. In the
case of fillet welds combined with a groove weld, the weld
root of the groove weld shall be used.
throat, theoretical (of fillet): the distance from the beginning of the joint root perpendicular to the hypotenuse
of the largest right triangle that can be inscribed within
the cross﹕ection of a fillet weld. This dimension is based
on the assumption that the root opening is equal to zero.

参照RCCM S 3834中的规定：
The throat dimension (a) is the shortest distance between the root of the weld and the external surface of the molten
metal. This value shall take account of any porosity (or inclusions), in accordance with figure SA 3834b), with in this
case:
a - Σ di > 0.66 e
Minimum leak path
l - Σ di > 0.66 e
with Σ di = sum of diameters of porosities or inclusions (for instance: Σdi = d1 + d2).
