Method for quality control of connections of elements with circular cross-section, magnetically impelled arc butt welded

摘要

Method of verifying the quality of the cross -sectional track -side couplings combined with a temporary rotating arch,in particular, connections of thin tube elements in the form of semiaxles and drive shafts with working ends in the form of short shafts or joints,where the qualitative assessment of the combination is based on an analysis of the ultrasound wave emitted from the ultrasonic warhead (7) at the time of the measurement towards the bogie is characterised by this,that the curved elements (1, 2) with rolls (3) are positioned and then rotated at least at the full angle at the measurement time,When measured, the ultrasonic wave is coupled with the flow of liquid directed at the flow rate, which is injected into the flow rate using a nozzle (6),where an ultrasonic head (7) generating a subsurface wave is placed in the wall of the sintered elements (1, 2).
