Example of application of the latest NDI
technique (1)
-"a$%' Array UT
•Equipment enable to set different transmission timing for each
probe by
electric control
•Equipment enable to set transmission angle freely so that it can
be applied
to narro! space e"en though normal probe can not be applied
due to
geometrical reason
•Equipment enable to set the depth of focus point and this
technique is
effecti"e measure for scanning of stainless steel
casting !hich is lesser permeability
