Destructive testing is time consuming and often provides inaccurate results. Ultrasonic Non-Destructive Testing test systems can help save companies time and money while providing a safer method with the most accurate results. The Right System […]
Gel-free couplant for Ultrasonic NDT testing of Spot Welds
Introduction Most Ultrasonic NDT systems use Gel Couplants to get a good signal connection between the probe and the spot weld. The problem with Gel Couplants is that they need to be cleaned thoroughly before the metal surface can be painted. There is also a cost for purchasing and maintaining inventory of the gel couplants. […]
Ultrasonic Signal Attenuation in NDT testing of Spot Welds
Introduction Ultrasonic NDT testing is an effective way to determine the integrity of a spot weld. Below is a good description of the attenuation or decrease in signal strength that can be useful when analyzing a spot weld. Attenuation Measurements Ultrasonic wave propagation is influenced by the microstructure of the material through which it propagates. The velocity of the ultrasonic waves is […]

NDT Ultrasonic test of Spot Welds to detect Stuck Welds
Introduction An important correlation between the attenuation of an Ultrasonic A-scan reading and the strength of a spot weld can help you identify “stuck welds” or “cold welds”. Many studies have been done over the years to better understand how Matrix Phased Array (MPA) ultrasonic NDT systems can pick up on different characteristics of a […]
Reliability of NDT Ultrasonic readings of Spot Welds
Introduction There are advantages and limitations for you to consider with ultrasonic technology to do NDT (Non-Destructive Testing) of spot welds. For the most part, you can count on a well-made Ultrasonic system to be a good solution to provide accurate results for spot welds Non-Destructive Testing. Fortunately, you don’t have to be an expert […]
NDE proven 95% as accurate as physical testing of Spot Welds
Introduction Non-Destructive Evaluation (NDE), also known as Non-Destructive Test (NDT) can provide you with 95% accuracy when compared to physical destructive testing of spot welds. The value of using NDE is that it is much quicker, safer, and easier than destructive testing. This requires that you have the right equipment; advanced systems make it easy […]
NDT Training is Important
Introduction Non-Destructive Testing (NDT) systems are becoming more advanced and more accurate; however, there is still a human component that you must address to make sure you are collecting good information. You can’t make good decisions about quality control if you don’t have confidence in the test data. Training your NDT technicians well is an […]
