Learn about non destructive testing.


Why do you need non-destructive testing of your castings, plastic or machined parts?


If you are manufacturing or buying castings or machined parts and are meeting a quality standard, especially for aerospace applications, then you need to be sure that quality is met. Look toward non destructive testing services.


Typically, the criteria that concerns you are surface appearance and integrity, soundness of sections, and accuracy of dimensions. Who set that standard? Why are you meeting it? Most of all, is that standard really necessary for the functionality of the part or is it just adding unnecessary cost?


Often, a part may be designed by someone unfamiliar with the casting process or the nuances of machining and they rely on published quality standards that may or may not be appropriate for the parts actual application. They may specify a quality level higher than the design really requires, which serves no purpose except to increase the cost. And if the designer is an expert, then how does the end client be assured that the quality that they are paying for is being met?


At American Metal Testing, we will help you meet a standard that you are trying to achieve. A more favorable price and delivery can be obtained by first selecting the material specification (preferably ASTM) which meets the mechanical test requirement, and whose scope encompasses the service for which the part is intended.


The necessary quality level can then be established by specifying special inspection procedures such as visual, magnetic particle, dye penetrant, or radiography testing procedures.


Surface discontinuities are the irregularities, imperfections, or cracks that are found on the surface of the casting. Although some are of such size that they can be seen visually, others are either not visible or go unnoticed without special inspection methods such as magnetic particle or liquid penetrant examination. For the examinations to be meaningful as a basis for purchase, all parties concerned must use inspection methods that are standard.


While various methods of nondestructive testing exist to measure mechanical properties, chemical composition, casting soundness or maximum service loads, a single test that encompasses all these factors does not exist. A combination of nondestructive methods may be required to document the soundness and quality of a casting or metal part.
