Table 3.

Defect classification follow-up priority, F, scheme defined as the product of the defect category, C, and directionality distribution, D. If F = 0, then a classification is assigned for the weld feature; if F = 1, then a low priority is assigned for follow-up (yellow-shaded cell); if F = 2, then a medium follow-up priority is required (orange-shaded cell); if F ≥ 3, then a high follow-up priority is required for signals from defects (red-shaded cell) [112,185].

Follow-up Priority F = C × D		Defect Category, C
		1	2	3
Directionality distribution (D)	0	0	0	0
	1	1	2	3
	2	2	4	6
	3	3	6	9
