Destructive Testing

Destructive testing (DT) refers to the application of controlled force, stress, or a similar condition to reveal the limits, strength, and failure points of a structural component or material. This brand of testing plays a key role in terms of safety and compliance for primary industries like automotive, construction, and aerospace. Inspec Testing Inc. is a reputable destructive testing company that serves California, Virginia, and Hawaii and offers a full range of highly effective DT services.

Tension Test

A tension test, or direct tension test, is a mechanical test that puts specific materials through their paces by pulling them to the breaking point, which measures all the following properties:

• Elongation
• Strength
• Point of fracture

Compression Test

A destructive compression test involves crushing a sample of a specific material to the point that it fails to determine its maximum compressive strength. In the process, yield point and rupture force, which are critical elements of structural design, are determined.

Macro Etch Test

Macro etch testing is a method of destructive quality control that employs acid to determine the internal structure of a metal, to verify its quality, and to identify any defects.

Fillet Weld Break Test

The fillet weld break test is a destructive testing method that applies specifically to welds. It’s used to determine weld quality, especially root fusion, and it’s performed by bending a T-joint to the point of failure. When this occurs, any internal flaws, like a lack of fusion, are revealed. At Inspec Testing Inc., we conduct fillet weld break tests according to all qualification standards.

Guided Bend Test

A guided bend test is a quality control method used in welding qualifications. The test assesses how sound the welds are by bending a sample around a shaft to see if there are any internal defects, such as cracks or porosity. The process puts the outer surface of the weld under pressure, and failure to successfully achieve the required angle signifies failure to meet the necessary welding standards.

Rockwell Hardness Test

The Rockwell hardness test presses a powerful indenter into the material being tested in order to measure resistance. This is determined in relation to the depth difference after applying a minor load that is followed by a major load, once the major load has been removed, while the minor load remains in place.
