Clarification on definition of weld joint thickness
Clarification on definition of weld joint thickness
(OP)
I have an E-beam weld joint between a bellows and a ring with the configuration shown in the attachment. I have an acceptance criteria of underfill shall be less than 10% of the joint thickness (ref. AMS 2681 para 3.7.6). Is the joint thickness defined by the depth of penetration specified (20mils) or joint thickness as shown in Figure 1? The vendor left a significant crater as shown in Figure 2. That crater is well below the original joint line. Is the threshold 2 mils (10% of 20mils) or 1.6 mils (10% of 16 mils)?

The reason why I view joint thickness as the esential variable is simply the function of the partial penetration weld in this application.
If you have a weld penetration size requirement to join the two items, which is 20 mils, lack of weld fill would be based on joint thickness regardless if it is a full or partial penetration weld.
