More options have developed in the way liquid penetrant inspection is performed nowadays. Liquid penetrant inspection (LPI), also known as dye penetrant inspection (DPI) or penetrant testing (PT), was...
Visible penetrants for liquid penetrant testing (PT) were evaluated at low temperatures. Previous testing of visible penetrant materials has been done using cleaners and developers with chlorinated solvents (now...
If you’re involved with magnetic particle testing (MT), then you’re familiar with the term “Ketos ring,” but do you know where the word Ketos comes from? Ketos® is actually...
This discussion will list and explain why each magnetic particle testing accessory is needed to validate the system performance of an inspection. Magnetic Particle Test Pieces Whether you are...
Toward the end of this decade, our industry will realize a full century since the inception of the magnetic particle inspection method. Since that discovery by Alfred Victor de...
Magnetic particle testing (MT) is a popular, low-cost method used to perform nondestructive testing (NDT) of ferromagnetic material. Ferromagnetic is defined in ASME Boiler and Pressure Vessel Code Section...
The advantages of magnetic particle testing using indirect magnetism may be offset by the part’s coating thickness. Magnetic particle testing (MT) is one of several nondestructive testing (NDT) methods...
When in doubt, always check with a certified Level III or contact your NDT product supplier. Alfred V. de Forest and Foster B. Doane developed the magnetic testing method...
Eddy Current Testing (ECT) is a nondestructive testing (NDT) method which uses the principle of electromagnetic induction to detect flaws in conductive materials. An excitation coil carrying current is...
It is essential that technicians be familiar with both the advantages and limitations associated with the eddy current testing process. Eddy current testing (ECT) is a widely accepted nondestructive...
