The main jia of the revision in the standard proper and the appendices for the cases of steel plate welded joints, the circumferential joints of steel pipes, the T-shaped joints of steel plates and the method of classifying flaw images by radiographs are described. Generally, qualitative analysis with reference artificial flaws. Easy for handling with portable devices. Temperature and humidity must be essential for testing.
Close Go to Workspace. For this test, the electromagnetic phenomenon is used and any coupling medium is not necessary. Magnetizing with perpendicular two direction is necessary for detection of each discontinuity.
UT Advantage Easy for detecting a plain type discontinuity. ET Advantage High speed test is available. Video Scope Video Scope. Weak Point Surface condition is affected to test results. 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.
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.
JIS Z – Methods of radiographic examination for welded joints in steel (FOREIGN STANDARD)
Results 1 – 1 of 1. Not applicable to fillet weld to top Test is applied on ferromagnetic materials only.
Local corrosion occurred on opposite side can be located and the remained wall thickness can be read by continuous searching. Coupling medium must be applied on surface of subjects for testing Generally, not evaluate the kind of discontinuity.
Cost for testing is lower than other methods.
310 of flaw’s height, spreading along to wall thickness direction can be got. Uis is able to perform automatically. This is a method to send ultrasounds to the ijs surface and receive the signal of subject flaws by a Normal transducer positioned perpendicular.
Methods of Radiographic examination for welded joints in steel. High speed test is available. Reference Number Reference Number. Standard Search Advanced Search. No electric power is required except for lighting in dark room. Plain type discontinuity like a crack, is not detected when the 310 has an angle usually over 15 degree to exposure direction of RT.
Weak Point Non-relevant signal and noise are disturbed evaluation. Normal Straight Beam method for Flaw detection This is a method to send ultrasounds to the tested surface and receive the signal of subject flaws by a Normal transducer positioned perpendicular. Limited to ferromagnetic materials. Cost for testing is lower than RT Radiographic Testing. Thinner coating covered a surface discontinuity is not disturbed for detecting by this method.
V Magnetic Particle Testing: Comparatively, cost for testing is higher than others. Non-relevant signal and noise are disturbed evaluation.

V Liquid Penetrant Testing: Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw. Surface and near surface discontinuity can be detected. Thicker coating must be removed before testing.
The revision of this standard was attempted several times, and the course of revision id described. Most economical method for tube inspection ji a heat exchanger to detect local corrosion and erosion.
MT Advantage Iis for testing is lower than other methods.
JIS Z 3104:1995 English Edition
Test is applicable from one side of objects. Test result is remained as persuasive record.
Easy to evaluate by visible indication appeared on tested surface. Discontinuities with several direction can be detected at once. Magnetic field is made by Electric AC Yoke.
