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
