Ultrasonic Inspector (Metal Non-Destructive Testing)
ちょうおんぱけんさいん
Industry & Occupation
Classification
Summary
A technical job that uses ultrasonic waves to inspect internal defects and thickness in metal parts and structures.
Description
Ultrasonic Inspectors (Metal Non-Destructive Testing) use ultrasonic flaw detection equipment to non-destructively detect and evaluate defects such as cracks, voids, and delaminations inside metal parts and structures. They transmit ultrasonic waves at frequencies suitable for the inspection target and analyze the received echo waveforms to determine the location and size of defects. Processes such as surface preparation of the sample, application of coupling material, setting of measurement conditions, and calibration using calibration blocks are important. They work in quality control departments, manufacturing sites, third-party inspection companies, etc., and handle a wide range of metal products such as welds, castings, and forgings.
Future Outlook
An essential occupation for quality assurance in manufacturing and ensuring the safety of social infrastructure. Demand is expected to remain stable due to advances in inspection automation and remote inspection technologies utilizing IoT and AI.
