Quality Inspector Trade Career Profile

ROLE OVERVIEW:
Quality Inspectors check manufactured parts against engineering drawings to ensure zero defects and high dimensional accuracy.

SKILLS REQUIRED:
- Measuring parts using high-precision instruments
- Reading engineering drawings with geometric tolerances
- Spotting visual casting and machining defects
- Recording data with statistical process control (SPC)

TOOLS USED:
- Vernier calipers, micrometers, and height gauges
- Thread gauges, plug gauges, and surface roughness testers
- Profile projectors and coordinate measuring machines (CMM)

GROWTH PROSPECTS:
Specialized QA inspector roles leading to EHS and senior auditor posts.

INTERVIEW QUESTIONS:
1. Q: What is the difference between Go and No-Go gauges?
A: A Go gauge must enter the part hole easily (verifying minimum limit), while a No-Go gauge must not enter the hole (verifying maximum limit).
2. Q: Explain the difference between accuracy and precision.
A: Accuracy is how close a measurement is to the true value; precision is how close repeated measurements are to each other.
