Method and device for ultrasonic nondestructive control of joint welding between two parts

摘要

At the same time, the first ultrasonic beam (() 14) is emitted from an ultrasonic transmitter () towards the welding between parts () 9 (() 7, 8,,),,The second angle (7a) between the second ultrasonic beam (() 15) and the surface normality (7a) of the part (7, 8) and the second angle of the surface normality (7a) of the part (7, 8). In case of echo (16) of welding failureThe first and second ultrasonic beams are continuously transmitted to determine which of the first and second beams produces an echo (. 16) representing the fault. The fault characteristics are determined by the echo of the echo source beam ((16). The controller includes a first housing (1a), which includes a first transducer and a second housing (1b), wherein the second transducer is connected by a flexible connecting device.An electronic package is used to supply power to the transducer and recover ultrasonic signals, in which a switch () 5 and a unit () 13 for generating pulses and processing ultrasonic signals received by the transducer are installed.
