AUTOMATED SYSTEM FOR MEASURING, DETECTING, CLASSIFYING, AND WARNING ABOUT WELD DEFECTS IN STEEL PIPE JOINTS

Abstract

The invention relates to an automatic system for measuring, detecting, classifying, and warning about the degree of defects in steel pipe welds on a high-speed production line based on the principle of measuring leakage flux using high-sensitivity magnetoelectric sensors, including: a pair of high-sensitivity magnetoelectric sensors consisting of two sensors measuring weld flux (2) and reference flux (3), a pair of rare earth permanent magnets (4) creating a magnetic field arranged on both sides of the steel pipe body (1), a soft iron ring (5) acting as a conductor of the magnet's magnetic field and simultaneously shielding the magnetic field affecting the sensor area, an electronic circuit for measuring and converting signals from the sensor, an electronic circuit (6) acting as a power supply and simultaneously measuring and processing signals for the pair of sensors, a central processor (7) analyzing signals from the sensor, determining the level of the measured signal and providing thresholds for classifying weld defects and returning product information through a visual display screen (10), and sending control commands to the warning system. lamp form (9),Sending control commands to the audible alarm system (8), and issuing control commands to the integrated fault marking and classification system (13) and converting signals for the computer system to store (11) and report data transmission (12) to the management center, the entire system is powered by direct power supply (14).
