Welding Inspector Certified Exam: Part A

Questions and Answers 100% Correct


Nondestructive examination - ✔✔Determines the suitability of a material or

compound without compromising its serviceability. Identifies flaws

discontinuities and other imperfections, then determines whether they

exceed the allowable tolerance of a specification. Ultrasonic testing is one

of the most common forms used.

Destructive examination - ✔✔The test specimen is damaged, destroyed, or

otherwise rendered unserviceable. Very useful for determining certain

aspects of steel quality like mechanical properties and strength.

Visual inspection - ✔✔Conducted before during and after welding by

trained and qualified CWI helps identify errors before they become

significant problems. If done consistently and regularly it can identify

problems before they start and generally results an acceptable work.

VT - ✔✔As a CWI performing visual inspection you will need to make sure

the WPS is qualified and applicable to the weldment, and that the welder is

adhering to his requirements through fabrication.
