Weld Inspection with EMAT Using Guided Waves

In the last decade, Electro Magnetic Acoustic Techn ology (EMAT) technology has come of age with tremen dous success in many applications. The following paper rovides information of EMAT technology used for th e inspection of thin welds in automated environments. Because of its efficiency in generating guided wave s without couplant or contacting the part, EMAT is an ideal choice for volumetric inspection of welds in high-v olume, automated environments.
