Giving You a Break
Spectrum offers these important destructive testing applications:
Tensile testing subjects the test sample to uniaxial tension until the point of failure is reached. Our tensile testing capabilities include wedge tensile testing, axial tensile testing, weld tensile testing, castings tensile testing, elevated temperature tensile, machined specimen tensile testing, full-size tensile testing and yield tensiles, plus heat treatment capabilities.
Spectrum performs fatigue testing on components and materials to simulate progressive and localized structural damage that occurs when a material is subjected to cyclic loading. Our fatigue testing methods include fracture toughness testing, rotating beam fatigue testing, strain controlled axial fatigue testing, stress controlled axial fatigue testing, and crack propagation rate (da/dN) testing.
Charpy Impact Testing
The Charpy impact test, sometimes called the Charpy v-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture.
Bend Testing determines the ductility or the strength of a material by bending the material over a given radius. Spectrum performs bolt bend testing, weld bend testing, and raw materials bend testing.
Destructive Weld Testing
Destructive weld testing requires the physical destruction of a completed weld in order to assess its characteristics. This type of testing is employed regularly for numerous applications, some of which include welding procedure qualification and welder performance qualification testing, sampling inspection of production welds, research inspection, and failure analysis. A variety of destructive weld testing methods are used to determine weld integrity or performance, typically involving sectioning or breaking welded components and evaluating various mechanical or physical properties.
