What is an EPOCH 650?

The EPOCH 650 is a lightweight, portable flaw detector built to be rugged and flexible for nearly any inspection. Some key physical features include: Large, full VGA resolution transflective display for vivid clarity in any indoor lighting and direct sunlight conditions.

What is an epoch 600?

The EPOCH 600 is mid-level, handheld ultrasonic flaw detector. Weighing only 1.68 kg (3.72 lb.), its horizontal case is built to withstand the rigors of very harsh environments. EN12668-1 plus features such as 400 V PerfectSquare tunable square wave pulser, digital filtering for enhanced signal-to-noise ratio.

What is the other name for ultrasonic flaw detector?

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves.

What is angle beam technique?

Angle beam testing is by far the most commonly used technique in ultrasonic flaw detection. Angle beam probes consist of a transducer and a wedge, which may be separate parts or built into a single housing.

What is UT in welding?

Ultrasonic Testing (UT) – This method of testing makes use of mechanical vibrations similar to sound waves but of higher frequency. A beam of ultrasonic energy is directed into the object to be tested.

Is ultrasonic testing accurate?

Under optimum conditions, commercial ultrasonic gages can achieve a level of accuracy as high as ±0.001 mm (0.00004 in.) and ±0.025 mm (0.001 in.) or higher in most common engineering materials.

What is probe angle?

Angle beam probes consist of a transducer and a wedge, which may be separate parts or built into a single housing. They use the principle of refraction and mode conversion at a boundary to produce refracted shear or longitudinal waves in a test piece as shown below.

What is phased array NDT?

Phased array is widely used for nondestructive testing (NDT) in several industrial sectors, such as construction, pipelines, and power generation. This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality.
