An ultrasonic inspection technique using a specially designed electromagnetic acoustic transducer (EMAT) launches and receives longitudinal ultrasonic waves into a thin metal wall or thin metal foil seal of a container, causing it to vibrate and launch ultrasonic compressional waves into liquid contained therein. The contents of plastic containers having a metal foil seal forming one wall are ...

However, EMAT gives relatively low transmitted ultrasonic energy, with low signal to noise ratio, and the induced energy is critically dependent on the probe proximity to the test object. These are not desirable properties for NDT (nondestructive testing) of civil infrastructures.

emat boiler tube inspection EMAT technology is an Ultrasonic Non Destructive Testing method that differs from traditional ultrasonics in the way the sound is generated. In conventional ultrasound technology a piezoelectric crystal is used to convert electrical energy into mechanical vibration.

Non-Contact Stress Measurement during Tensile Testing Using an Emat for SH 0-Plate Wave and Lamb Wave. DOI: 10.4236/jst.2011.13009, PP. 65-70

A method and an assembly for inspecting welds between welded tubular ends comprises arranging a series electromagnetic acoustic transducer (EMAT) (7a, 8a, 7b, 8b) assemblies in circumferential direction adjacent to an inner and/or outer surface of at least one of the welded tubular ends and inducing the EMAT assemblies to transmit sequentially or simultaneously acoustic shear wave signals ...

inspection of thin welds in automated environments. Because of its efficiency in generating guided waves with out couplant or contacting the part, EMAT is an ideal choice for volumetric inspection of welds in high-volume, automated environments.

Abstract: An EMAT that generates horizontally polarized shear ultrasonic waves is combined with a PZT that generates longitudinal ultrasonic waves to provide simultaneous or sequential inspection of a test component material for improved accuracy in estimating properties of the material or detecting and estimating the dimensions of defects in the material.

INIS Repository Search provides online access to one of the world's largest collections on the peaceful uses of nuclear science and technology. The International Nuclear Information System is operated by the IAEA in collaboration with over 150 members.

Each of our certified Ultrasonic Shear Wave and Phased Array technicians has passed a blind test that includes four test specimens. The technician is asked to find, properly size and characterize at least eight real world flaws when testing. This provides assurance of the highest quality technician that Amerapex Corporation puts on your job site.

EMAT (Electro Magnetic Acoustic Transducers) inspection technique can be used on carbon steel as well as exotic alloys such as 9 Cr, 5 Cr and 304L. Due to the use of magnetism to induce sound into a test piece the EMAT pitch-catch ultrasound can maintain acoustic contact with the rough surfaces, inspect a narrow area, and can scan faster than ...

Newly developed portable Ultrasonic Testing (UT) units could drastically alter welding workflow by allowing weld inspection as often as after each pass. Normal weld inspection at depth, called “Volumetric Testing,” normally requires X-ray or ultrasonic test setups. Both normally require specialized equipment be brought to the site and the ...
