Abstract
The invention relates to the nondestructive testing and may be used for testing the weld with reinforcing bead.The method for ultrasound testing of the weld with reinforcing bead consists in that the acoustic system of the ultrasonic flaw detector, containing at least two transducers, is firstly installed onto the standard specimen, oriented to the weld. There are emitted ultrasound oscillations, there are detected the echo signals, it is determined the threshold of operation of the automatic indicator of the flaw detector, carrying out damping of surfaces of the reinforcing bead with an elastic protector. Then the acoustic system is installed onto the tested article and are carried out the same operations, there are compared the amplitudes of the detected signals with the threshold of operation and according to the obtained result it is appreciated the weld's quality. At the same time, the damping is carried out by relative displacement along the weld of the elastic protector, made as a rotatable roller of a material with high attenuation of the ultrasound oscillations, through a wetting liquid, embracing the weld's edge and retaining the roller against its surface with a force providing for the decrease of the echo-signals level from the weld's edge and from the rugosity of the reinforcing bead with at least 6 dB from the determined threshold of operation. The displacement of the roller over the weld surface is carried out in synchronism with the displacement of the transducers.
