B) !GSCC indications will walk (travel on the CRT) from 10 toward 00. When the search unit is angulated (per Figure 4) while the C) indication is peaked, a geometric indication will decrease in amplitude rapidly with a variation in incident angle. An indication caused by IGSCC tends t'J decrease in amplitude slowly and become rcre bro 6d based as the search unit is angulated. At times, an indication will separate from an IGSCC D) indication, as the search unit is moved toward the ( indication, and walk toward the 00. This indication, when it appears, is indicative of a crack tip and f s associated O with indications of !G5CC. 1 1 I
