Materials Engineering, Evaluation, and Inspection
Spectrum uses Ultrasonic Testing (UT) methods, including resonance and pulse-echo, to detect surface and marginally subsurface flaws in a variety of materials. Typical inspections involved welds, tubing, joints, valves, castings, billets, forgings, shafts, structural components and pressure vessels. Spectrum is able to determine thickness and mechanical properties while monitoring service wear and deterioration due to corrosion or erosion without removal or disassembly of the component.
UT gauges material thickness based on the time required for sound emitted from the transducer to travel through the component and back to the transducer. UT inspections can be performed on both metallic and non-metallic surfaces, such as wood and concrete, depending on the acoustic properties of the material.
