The invention discloses a
phased array, TOFD and
magnetic powder integrated detection
system and method for medium and large
diameter pipeline welded joints, the detection
system comprises a
control system, a
liquid storage and supply
system and a scanning system, the
control system is connected with the
liquid storage and supply system, the
control system is connected with the scanning system, and the scanning system is connected with the control system. The
liquid storage and supply system is connected with the scanning system through a flexible water pipeline and a flexible magnetic suspension pipeline; the liquid storage and supply system comprises a magnetic suspension tank and a water tank which are respectively used for storing magnetic suspension and water; the scanning system is a
data acquisition center, is provided with a
phased array probe, a TOFD probe, an electromagnetic yoke and a video sensor in a centralized mode, operates in a sub-
control mode, is driven by a magnetic attraction wheel driving mechanism to achieve automatic scanning of a
welding joint, and transmits detection
data information to the control system. The device is compact in structure, convenient for later maintenance and low in manufacturing cost; according to the invention, the
parameter control is accurate, the detection data can be analyzed in real time, the
data interpretation is convenient, the detection precision is high, the detection speed is fast, and safety and reliability are realized.
