Weld root penetration acceptance criteria

Post by octane »

What is the acceptance criteria for weld root penetration as per ASME B31.3?
When it is considered as incomplete and when excessive?

The criteria has been clearly mentioned in Table 341.3.2 of ASME B31.3.
It depends on the thickness of the weld as I have attached the reference screenshot.
Refer to this and let me know if there is any query.
