The paper presents results of studies demonstrating a significant impact of double transducer probe characteristics on the interpretation of discontinuity types in the ultrasonic quality control of forgings. Double transducer probes are characterised by significant differences in the width of an ultrasonic beam in two mutually perpendicular directions, i.e. perpendicular and parallel to the plane...
The articles presents issues related to ultrasonic testing of welded joints and includes results of tests dedicated to the detectability of flat discontinuities depending on their orientation in relation to the ultrasonic beam axis. In the tests, flat discontinuities were constituted by circular flat-bottomed reflectors of DGS-45° standard having a diameter DDSR=2 mm. The tests were performed using...
The article presents test results related to the detectability of flat discontinuities depending on their orientation in relation to the axis of an ultrasonic wave beam. The flat discontinuity used in the tests was the skew surface of a DGS standard, being an infinite reflector for an ultrasonic wave. The tests were performed using a Phased Array transducer and a defectoscope with a Phased Array imaging...
Basic factors which have an influence on conducting manual ultrasonic testing of joints in the welded constructions are presented in the following article. These factors are specified on the base of the guidelines referring to conditions and methods of carrying out examinations which are currently in force in the following standards PN-EN ISO 17640 and PN-EN ISO 22825. Due to the vastness of subject...
The article presents the analysis of guidelines contained in PN-EN ISO 17640 related to ultrasonic tests of welded joints with reference to aligning the angle of beam introduction into a weld fusion line as well as the results of tests investigating the bevelling angle effect on the amplitude of echo bounced off the bevelled surface simulating the echo bounced off incomplete side fusions. The tests...
Quality assurance systems in welding engineering demand that the manufacturers of welded structures and welding equipment should apply qualified welding technologies. The most commonly used mode of welding technology qualification is testing a given welding technology by making test joints and carrying out their examination. This article presents the analysis of test joint dimensions recommended in...
