The recommended method is suitable for most welding processes and connector styles. The variables related to the basic method will affect the sensitivity of the inspection, as shown in Appendix A. Welds of geometrical shapes shown in Tables 1, 2 and 3 may be directly inspected by the methods specified in this standard. Defect magnetic
