Scott Cargill, Past President of ASNT shared the below auto-ignition story with us. It is well worth the read. Auto-Ignition? What’s that? Wait a minute, I’m almost positive it has something to do with the MSDS – Materials Safety Data Sheet (old school) or with the harmonized global system of today just SDS – Safety […]

SuperSoniX™ – A new UT Couplant with a Historic Name
In May of 1940, Floyd Firestone, a Professor in the department of Physics at the University of Michigan, filed US patent 2280226 in which he described an instrument for the detection of flaws and measuring thickness in metal objects. Dr. Firestone used the term “Supersonic Vibration Waves” to describe what we now refer to as […]
Selecting the Correct High Temperature UT Couplant
When performing UT inspections at elevated temperatures, it is critical to select the correct couplant, both for performance and safety. Thickness gauging and corrosion mapping are often conducted at temperatures between 500°and 1000°F (260° and 538°C) where auto-ignition may occur. Ultrasonic transducers and instruments capable of operating at temperatures up to 950°F (510°C) are routinely […]
Silver Bullet Couplants – for inspections that are almost impossible without the right couplant.
Many UT applications require a specialty UT couplant. For difficult inspections that require high acoustic impedance, shear wave, reduced surface noise, extreme temperature range or extended service life for sensors, we have the right couplant. High Impedance Couplant: A high impedance couplant typically has an acoustic impedance above 3.5 M Rayls. Water based couplants typically have […]

Mixing UT powder couplant doesn’t need to be complicated
EchoMix Single is a unique one-part powder ultrasonic testing couplant that easily mixes in cold water in 5 minutes. It is less expensive to ship than pre-mixed couplants, and it includes a special component to ensure uniform mixing. Here’s more on what makes EchoMix Single stand out: Its simple mixing process reduces errors. EchoMix Single […]
Solving issues with wedge and part coupling failure in phased array inspections
During phased array testing, element dropout can be a problem. Common causes include dead elements in the transducer or a failure of the wedge-to-transducer or wedge-to-inspection-part coupling. Let’s look at each of these coupling failures in detail before offering some solutions for each of these PA testing issues. Wedge-to-transducer coupling failure is often partial and […]
VersaSonic is a leading high temperature couplant, but … read how Caterpillar and power generation equipment manufacturers are using it.
VersaSonic, the most versatile ultrasonic testing couplant available, will now be used in even more environments after recent developments. Caterpillar Inc., the well-known equipment and engine manufacturer, has approved VersaSonic for use on its CAT equipment. Caterpillar is distributing VersaSonic through its dealers worldwide for UT thickness gauge inspections in harsh environments, from sub-zero to […]
New Fluids for NDT can eliminate fire, smoke and residue
Echo Ultrasonics has recently become the exclusive distributor of SpectrumGlide AUT-NDT Fluid Couplant in the U.S. and Canada. SpectrumGlide, developed by Eclipse Scientific, has a viscosity formulated to reduce runoff and provide longer dwell time at temperatures from -50° F to 730° F (-45° C to 387° C). The addition of SpectrumGlide gives Echo Ultrasonics […]
Looking for the right fluid for your AUT Inspections?
Echo’s automated ultrasonic testing fluids offer solutions for those who’ve encountered problems with other fluids. Often, fluids are too thick to pump, run off too fast, smoke too much, auto-ignite, freeze or vaporize so quickly that there’s no time to conduct the inspection. With AUT fluids in multiple viscosities (thicknesses) spanning a broad range of […]
