Non-destructive testing of welded metal components is an area where significant cost savings can be made if preparation costs can be minimised. The largest cost associated with preparation is grinding off the weld cap in order to facilitate the detection of defects that may be present just under the cap. In addition, there are also potential savings to be made if the actual testing time can be reduced or if the tests can be performed at elevated temperatures beyond which conventional contacting ultrasonic techniques can be practically used. This paper describes a non-contacting NDT method using a pulsed laser and an electromagnetic acoustic transducer (EMAT) which has the potential to interrogate the entire cross-section of a weld.
