Certified Mechanical Inspector

Mechanical inspectors work in the manufacturing industry to ensure the proper function of parts and equipment. Day-to-day duties may include working with quality engineers, evaluating hardware documentation, inspecting products, measuring process performance, recording data, and preparing reports. Other tasks might include offering basic system support.

The majority of mechanical inspectors work full-time during regular business hours, although some positions require evening or weekend work. Depending on the workspace where inspections are to be completed, inspectors might be exposed to chemicals, eye and skin irritants, and loud noises; precautionary gear and clothing are required. Work hours are shared between inspections of manufacturing plants and office hours, during which time mechanical inspectors write up reports.

Let's trace the steps to become a mechanical inspector.

Step 1: Complete Postsecondary Education

Some employers prefer to hire candidates with vocational training. Certificate programs for aspiring mechanical inspectors can be found at community colleges and vocational schools. Coursework is designed to teach students skills in blueprint reading, calibration, inspection and testing, technical math, and metrology.

Classes may also cover topics like applied technical mathematics, introduction to machine tools, and mechanical inspection. Some training programs offer more specific courses that include inspection of bolting and fasteners, tubing and piping inspections, valve inspections, and inspection results reporting.

Step 2: Gain Experience

According to the American Society for Quality (ASQ), in order to be eligible for the Quality Inspector designation, candidates must have at least two years of experience in mechanical inspection or a similar field. This allows candidates to build a solid foundation for a career in mechanical inspection by gaining hands-on experience operating measuring machines, using calibration equipment, interpreting blueprints, planning inspections, and evaluating quality. Employers also look for applicants with experience in related areas, such as inspection and mechanics.

Success Tip:

Begin preparing for the certification exam. ASQ offers online resources to help certification candidates prepare for the test, including online access to the Quality Inspector Body of Knowledge. ASQ also offers preparatory courses and links to books that can help prepare aspiring mechanical inspectors for the exam.

Step 3: Get Certified

The ASQ Quality Inspector certification exam contains 100 multiple choice-questions. Candidates are given four hours to complete the open-book test. Questions cover inspection and testing, metrology, technical math, and quality assurance. The exam is designed to gauge candidates' knowledge and comprehension, as well as their ability to apply, analyze, and synthesize ideas. The ASQ certification is a lifetime certification that does not require renewing.

To recap, aspiring mechanical inspectors might benefit from vocational training. After gaining experience, inspectors can test for the Quality Inspector designation, which is a lifetime certification.
