What is the Minimum Thickness Ultrasonic Testing Can Measure? 

Understanding the minimum thickness ultrasonic testing can measure is sometimes required in order to remain compliant with maintenance regulation. Ultrasonic testing uses subsonic vibrations to calculate the thickness of a test component. By knowing the wavelength and measuring the time taken for it to return through an object, the object’s thickness can be determined. This is important when checking for corrosion or inconsistencies within the structural integrity of an object. NDT equipment, project specifications and the construction code used for manufacturing the test part all can give some indication about the minimum thickness ultrasonic testing can measure.  

NDT Equipment Limitations 

NDT equipment comes in a vast range of configurations which measure wavelengths of different values. By referring to your equipment’s manual, you should be able to get an indication of the minimum thickness it can measure. If you are buying NDT equipment for the purposes of measuring part thickness, be sure to consult your supplier to ensure that the equipment you purchase is capable of measuring the parts you need it to. NDT Australia is able to consult you in this regard when you call our friendly sales staff. 

Project Specifications 

A project specifications document describes the needs, objectives, constraints, expected features and deadlines, as well as other information; of an engineering, manufacturing or civil  project. Project specifications are delivered before commencement of a project and may or may not give an indication of the minimum part thickness non-destructive testing equipment must be capable of measuring. Acquisition managers can consequently refer to project specifications to ensure that only effective NDT equipment is purchased. However, if project specifications documents do not emphasise the minimum thickness ultrasonic testing can measure, engineers can refer to the part’s construction code to determine this value. 

Part Construction Codes 

Part construction codes often give an indication of the minimum thickness that can be measured by ultrasonic non-destructive testing. Minimum thickness values will be outlined verbatim in the construction code if they are included at all. 

As an ultrasonic testing operator, it is wise to refer to non-destructive testing procedure documentation before beginning a job. This is because knowing the minimum thickness that can be evaluated using ultrasonic Inspection is crucial to ensure compliance with maintenance regulation and that equipment is not purchased unnecessarily. If there is no relevant information included in non-destructive testing procedure documentation, the NDT operator may check project specifications or construction codes used during manufacturing of the part to determine the minimum part thickness NDT can measure.
