[0002] Steel structures are building structures made of steel materials. When assembling or splicing steel structures, welding is required to connect or reinforce the steel components. Welding defects often exist at the weld joints, which can reduce the quality of the steel structure.

[0003] Currently, ultrasonic testing is a widely used non-destructive testing technology, suitable for detecting internal defects in steel structure welds.
