Application of ultrasonic testing in nondestructive testing of welds in building steel structures
Ultrasonic testing technology is based on the principle of ultrasonic propagation in materials.It detects defects in welds by emitting ultrasonic pulses and receiving reflected signals.These reflected signals can provide information about the internal structure and defects of welds,such as cracks,air holes,slag inclusions,etc.Based on this,this article first elaborates on the principle of ultrasonic testing,and then analyzes the properties of weld defects from three aspects:defect characteristics,defect waveform,and bottom wave.Finally,combined with specific engineering cases,the application of ultrasonic testing in the detection of welding seams in building steel structures is analyzed and discussed.
