GB/T 31932-2015
ActiveMethod for electromagnetic automatic ultrasonic testing for thicker steel plates
厚钢板电磁超声自动检测方法
Application Summary AI generated
This standard specifies the method for using electromagnetic acoustic transducers (EMATs) to automatically detect internal and surface defects in thicker steel plates, typically those over 6 mm in thickness. It is applied in the metallurgical industry for quality control during the production of heavy steel plates used in shipbuilding, bridges, pressure vessels, and large-scale construction. The method enables non-contact, high-speed inspection without the need for liquid couplants, making it suitable for inline testing at elevated temperatures.
