If the discontinuity is longer than 1 inch, what must be done?

Explanation:
When a discontinuity is longer than a set limit, you must determine how deep it runs to judge its severity and decide on the proper action. Exploring the discontinuity to a depth of 1 inch (25 mm) provides a controlled, objective measure of its extent. This depth check helps reveal whether the flaw is shallow or extends deeper, which in turn informs whether the weld can be repaired or must be rejected or replaced. Skipping investigation, proceeding with the weld, or ignoring the defect could allow a hidden flaw to compromise integrity, and replacing the entire plate is only warranted if the flaw is unacceptable after evaluation.
