Abstract

As steel structures are widely used in construction and many other fields, the quality of welds has become a core factor concerning structural safety. Non-destructive testing techniques can accurately detect weld defects without damaging the workpiece. This article will detail the principles, advantages, and limitations of common inspection methods such as ultrasonic, radiographic, magnetic particle, and penetrant testing. It will also conduct an in-depth comparative analysis of their practical applications in different scenarios, providing scientific evidence to ensure the quality of steel structure welds and optimize inspection procedures, thereby assisting the industry in improving engineering quality.
