Post-Cleaning is necessary for rotating equipments to remove the particle. No electric power is required except for lighting in dark room. Weak Point Accessibility for both side of test object is required.
JIS Z 3104:1995 English Edition
UT Advantage Easy for detecting a plain type discontinuity. Search coil works in tubes without contact and corresponds quickly to the applied test frequency.
Test is applied on ferromagnetic materials only. Easy for detecting a plain type discontinuity. Video Scope Video Scope. Magnetizing with perpendicular two direction is necessary for detection of each discontinuity.
JIS Z – Methods of radiographic examination for welded joints in steel (FOREIGN STANDARD)
Surface and near surface discontinuity can be detected. Weak Point Surface condition is affected to test results. At last, this revised standard was instituted on 3140 1, by investigating the present status in Japan and foreign countries by the cooperation of the related organizations and experts, and considering the compatibility with the international standards, based on the WES standards which are enumerated.
Methods of Radiographic examination for welded joints in steel.
Publication Year Publication Year. Generally, qualitative analysis with reference artificial flaws. Information of flaw’s height, spreading along to wall thickness direction can be got. Required to remove the coating and foreign material inside a flaw completely before testing. Not disturbed to the thickness of thicker subjects. Limited to ferromagnetic materials. Sectional drawing for corroded area and longitudinal location of such corrosion can get visibly on CRT.
Kind, shape and dimension of discontinuity can not be identified from test results. Get permanent URL for this record. Easy to evaluate by visible indication appeared on tested surface.

Invisible fine discontinuity can be detected by a magnified indication with surpass contrast on proper background. This is a method to send ultrasounds to the tested surface and receive the signal of subject flaws jix a Normal transducer positioned perpendicular.
High speed test is available. Non-relevant signal and noise are disturbed evaluation. PT Advantage Easy to apply in field testing when used portable set. Comparatively, cost for testing is higher than others.
Results 1 – 1 of 1. Jiss to apply in field testing when used portable set. MT Advantage Cost for testing is lower than other methods.
Skilled technician is required to conduct testing. Round type discontinuity can be detected easily. Test is able to perform automatically.
