Thinner coating covered a surface discontinuity is not disturbed for detecting by this method. Test is applicable from one side of objects.
Reference Number Reference Jid. Weak Point Surface condition is affected to test results. Weak Point Non-relevant signal and noise are disturbed evaluation.

Generally, qualitative analysis with reference artificial flaws. Normal Straight Beam method for Thickness gauging Continuous scanning on interest jie Local corrosion occurred on opposite side can be located and the remained wall thickness can be read by continuous searching.
Test is able to perform automatically.
Non-relevant signal and jie are disturbed evaluation. Temperature and humidity must be essential for testing. Accessibility for both side of test object is required.
Easy for detecting a plain type discontinuity. Please provide a name for this query: Round type discontinuity is difficult for detection. Methods of Radiographic examination for welded joints in steel. Angle Beam Method for Flaw detection Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw.
Easy for handling with portable devices. Invisible fine discontinuity can be detected by a magnified indication with surpass contrast on proper background. Easy to evaluate by visible indication appeared on tested surface. The constitution of the standard is explained. 33104 type discontinuity like a crack, is not detected when the face has an angle usually over 15 jix to exposure direction of RT.
Weak Point Limited to ferromagnetic materials. V Liquid Penetrant Testing: Limited to ferromagnetic materials. Easy for evaluating the kind of discontinuity from test results. Internal Rotary Inspection System IRIS Ultrasonic transducer inserted into a tube can read the degree wall thickness via a rotating mirror attached to water turbine that is worked by pressure water.
Weak Point Required to remove the coating and foreign material inside a flaw completely before testing. High speed test is available. Comparatively, cost for testing is higher than others.
The revision of this standard was attempted several times, and the course of revision id described. Jls and near surface discontinuity can be detected.
ET Advantage High speed test is available. Cost for testing is lower than other methods. Not applicable to fillet weld to top Test is a on ferromagnetic materials only.
Normal Straight Beam method for Flaw detection This is jiss method to send ultrasounds to the tested surface and receive the signal of subject flaws by a Normal transducer positioned perpendicular. Round type discontinuity can be detected easily. Easy for detecting a superficial discontinuity. Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw.

Get permanent URL for this record. UT Advantage Easy for detecting a plain type discontinuity. Test result is remained as persuasive record. Local corrosion occurred on opposite side jie be located and the remained wall thickness can be read by continuous searching.
JIS Z 3104:1995 English Edition
Coupling medium must be applied on surface of subjects for testing Generally, not evaluate the kind of discontinuity. Cost for testing is lower than RT Radiographic Testing. Ultrasonic transducer inserted into a tube can read the degree wall thickness via a rotating mirror attached to water turbine that is worked by pressure water. Surface condition is affected to test results. Discontinuities with several direction can be detected at once. Skilled technician is required to conduct testing.
PT Advantage Easy to apply in field testing when used portable set. Post-Cleaning is necessary for rotating equipments to remove the particle. V Magnetic Particle Testing:
