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 evaluating the kind of discontinuity from test results. Not applicable to fillet weld to top Test is applied on ferromagnetic materials only.
V Magnetic Particle Testing: Skilled technician is required to conduct testing. No electric power is required except for lighting in dark room.
Please provide a name for this query: Search coil works in tubes without contact and corresponds quickly to the applied test frequency. Magnetizing with perpendicular two direction is necessary for detection of each discontinuity.

Test is able to perform automatically. Weak Point Surface condition is affected to test results. Thinner coating covered a surface discontinuity is not disturbed for detecting by this method.
Accessibility for both side of test object is required. Weak Point Accessibility for both side of test object is required. Cost for testing is lower than other methods. Required to remove the coating and foreign material inside a flaw completely before testing.
The main points 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. Test is applicable from one side of objects.
Discontinuities jsi several direction can be detected at once. ET Advantage High speed test is available. Easy for detecting a plain type discontinuity. Revised standard, JIS Z Get permanent URL for this record.
JIS Z 3104:1995 English Edition
Easy for detecting a superficial discontinuity. PT Advantage Easy to apply in field testing when used portable set.
A magnified and visible indication that was built up with magnetic 31004 in magnetic flux leakage can be detected easily. Post-Cleaning is necessary for rotating equipments to remove the particle. Magnetic zz is made by A AC Yoke. Round type discontinuity can be detected easily. The revision of this standard was attempted several times, and the course of revision id described. The basic policy of the revision is the adoption of the latest technology of radiography, the compatibility with the ISO standards as far as possible and the standardization of testing methods and technical matters which are not standardized.
Surface and near surface discontinuity can be detected. Reference Number Reference Number. Methods of Radiographic examination for welded joints in steel. At last, this revised standard was instituted on February 1, by investigating the present status in Japan and foreign countries by the cooperation of the related organizations and experts, and considering the compatibility ji the international standards, based on the WES standards which are enumerated.
Internal Rotary Inspection System IRIS Ultrasonic 31044 inserted into a tube can read the degree wall thickness via a rotating mirror attached to water turbine that is worked by pressure water.
Easy to evaluate by visible indication appeared on tested surface. Weak Point Required to remove the coating and foreign material inside a flaw completely before testing. Test is applied on ferromagnetic materials only. Most economical method for tube inspection of a heat exchanger to detect local corrosion and erosion.
Weak Point Non-relevant signal and noise are disturbed evaluation. Not applicable to fillet weld. V Eddy Current Testing: Limited to ferromagnetic materials. Comparatively, cost for testing is higher than others. Generally, qualitative analysis with reference artificial flaws.
The constitution of the standard is explained. Coupling medium must be applied on surface of subjects for testing Generally, not evaluate the kind of discontinuity.
Kind, shape and dimension of discontinuity can not be identified from test results. Close Go to Workspace. Temperature and humidity must ji essential for testing.
