Introduction

As an important part of non-destructive testing, ultrasonic guided wave testing technology is widely used in petroleum, chemical industry, electric power, marine engineering, transportation, etc: Detection of internal and external defects in waveguide structures such as pipelines, rails, plates and shells in the field, and detection in inaccessible areas such as covered layers and hidden shielding It has outstanding advantages, and has a long single detection distance and high work efficiency, providing an important technical means to ensure the safe operation of equipment: Ultrasonic guided wave detection technology includes magnetostriction, piezoelectric ultrasound, electromagnetic ultrasound, laser ultrasound and other methods: GB/T 31211 is intended to consist of two parts: --- Part 1: General: The purpose is to specify the ultrasonic guided wave to tubes, bars, plates, wires, profiles and other cross-sectional geometry specifications The overall requirements for testing structural parts: --- Part 2: Magnetostrictive method: The purpose is to specify the magnetostrictive ultrasonic method for quickly finding the cross-sectional loss in the component: Wave detection method: This document is part 2 of GB/T 31211 and specifies the specific technical requirements for the magnetostrictive ultrasonic guided wave testing method: GB/T 28704-2012 was revised for the first time, and GB/T 31211 ultrasonic guided wave testing standard system was established, which clarified the requirements for magnetostrictive ultrasonic guided wave testing: The technical requirements of magnetostrictive ultrasonic guided wave detection should be fulfilled to play its technical support role in magnetostrictive ultrasonic guided wave detection, so as to better promote the Promote the application of wave detection technology: Non-destructive testing Ultrasonic guided wave testing Part 2: Magnetostriction method
