3.5. Precautions

Try these first

1. 1.

   What is the significance of drill alignment?

   Hint

   Think about the consequences of misalignment.

2. 2.

   Why is water cooling used during drilling?

   Hint

   Consider what happens when heat builds up.

3. 3.

   What is the importance of drill alignment during non-destructive testing?

   • It decreases testing time.
   • It ensures accurate sampling.
   • It enhances surface texture.

   Hint

   Think about how misalignment could affect results.

4. 4.

   True or False: Water cooling is necessary to prevent micro-cracks during drilling.

   • True
   • False

   Hint

   Consider the effects of heat on materials.

5. 5.

   Design a training program for engineers on the precautions necessary during non-destructive testing, considering the physical and practical aspects.

   Hint

   Think about what skills are necessary for safe and effective NDT.

6. 6.

   Evaluate a case where an engineer ignored water cooling and realigned the drill improperly. Assess the potential implications and future steps that could be taken.

   Hint

   What long-term implications could arise from neglecting these precautions?
