Invisible fine discontinuity can be detected by a magnified indication with surpass contrast on proper background.
Methods of Radiographic examination for welded joints in stee..|INIS
Not applicable to fillet weld. Easy to evaluate by visible indication appeared on tested surface. Required to remove the coating and foreign material inside a flaw completely before testing.
Easy for detecting a plain type discontinuity. Generally, qualitative analysis with reference artificial flaws. No electric power is required except for lighting in dark room. UT Advantage Easy for detecting iis plain type discontinuity. Video Scope Video Scope. Careful application according to a test procedure is required for getting proper test results.
JIS Z 3104:1995 English Edition
Cost for testing is lower than other methods. ET Advantage High speed test is available.
Revised standard, JIS Z Test is able to perform automatically. Cost for testing is lower than RT Radiographic Testing. Kind, shape and dimension of discontinuity can not be identified from test results. Most economical method for tube inspection of a heat exchanger to detect local corrosion and erosion. Temperature and humidity must be essential for testing. Easy for detecting a superficial discontinuity.
Non-Destructive Testing | SANKI MARINE SERVICE INC.
Magnetic field is made by Electric AC Yoke. PT Advantage Easy to apply in field testing when used portable set. Thicker coating must be removed before testing. Not disturbed to the thickness of thicker subjects. Easy for handling with portable devices.
The constitution of the standard is explained. Results 1 – 1 of 1. Close Go to Workspace. Weak Point Accessibility for both side jix test object is required. Normal Straight Beam method for Thickness gauging Continuous scanning on interest area Local corrosion occurred on opposite side can be located and the remained wall thickness can be read by continuous searching.
Local corrosion occurred on opposite side can be located and the remained wall thickness can be read by continuous searching. Discontinuities with several direction can be detected at once. Standard Search Advanced Search. Round type discontinuity is difficult for detection. V Magnetic Particle Testing: Weak Point Non-relevant signal and noise are disturbed evaluation.
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.
Thinner coating covered a surface discontinuity is not disturbed for detecting by this method. Test result is remained as persuasive record. Reference Number Reference Number. Magnetizing with perpendicular two direction is necessary for detection of each discontinuity. Surface and near surface discontinuity can be detected. 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.
Weak Point Surface condition is affected to test results. Share mode ultrasound is sent with specified angle, 45, 60, 70 degree, and operator received a signal from flaw.
Easy to apply in field testing when used portable set. Easy for evaluating the kind of discontinuity from test results.
Please provide a name for this query: Round type discontinuity can be detected easily.
