It's quite straight forward. On 3 points: Get the reflection at half-skip .. mark. Get the reflection at full-skip .. mark. Get the reflection at 1 1/2 skip mark. Proceed to deeper holes and repeat. On 2 points ID-OD notch: Same procedure basically. Before all that make sure your index point is marked on the probe and that you have set the sensitivity at 80% FSH.
It's all depends on acceptance criteria... Just take the example of ISO ISO 23279 and ISO 11666, in accordance with afore stated standards all planner indications are not acceptable. and Lack of side wall fusion falls under Planner Category.
@@allwinthivan6795 yes if you are doing UT as per ISO standards and your acceptance criteria is ISO 11666. Remember same rule doesn’t apply if you are doing UT in accordance with AWS D1.1. Even In AWS D1.1 there are different, different criteria, base on structural loading such as static / cyclic etc. So As I mentioned earlier it’s depends on Acceptance criteria and governing code against which Examination is being performed.
