NDT of Spot Welds need to be Fast and Accurate
It is important to have a way to test spot welds quickly and accurately to determine the integrity of the weld. This is also true
Operational Principles of Ultrasonic NDT of spot welds
Analogy to Light waves: You can think of the ultrasonic waves (or signals) as being similar to light waves. Light waves emitted from the sun
Ultrasonic NDT use of gates to detect flaws in Spot Welds
Nondestructive testing using ultrasonic NDT systems with gates help to determine the integrity of a spot weld and whether a spot weld has any cracks
Ultrasonic NDT testing Spot Welds in Automotive industry
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating spot welds without destructing the weld, so the part can still be used after
Spherical MPA ultrasonic probe improves NDT speed, accuracy
Ultrasonic Non-Destructive Testing (NDT) is becoming popular with automotive manufacturers to verify the integrity of a resistance spot weld of advanced high strength steels. Systems
Non-Destructive testing (NDT) of Spot Welds
Traditional destructive testing of Spot Welds, such as those detailed in ISO 10447 https://www.iso.org/standard/61276.html are common in automobile manufacturing, and include peel and chisel tests
Ultrasonic NDT of Spot Welds can be more accurate than destruction testing.
With a good ultrasonic Non-Destructive Test (NDT) inspection system that determines the thickness and diameter of a spot weld, the results have been shown to
