[0002] Steel structures, with their advantages of high strength and fast construction speed, are widely used in large-scale buildings, bridges, and other projects. In steel structure construction, the quality of welds directly affects the stability and safety of the entire structure. When inspecting the appearance of steel structure welds, project supervisors need to carefully observe the weld surface for defects such as cracks, porosity, slag inclusions, and undercut.

[0003] Currently, conventional inspection methods mainly rely on visual observation and weld size inspection using measuring tools. Size inspection mainly includes weld reinforcement height, width, misalignment, and other dimensional indicators. Visual observation involves using a magnifying glass to magnify the weld and carefully observe the weld surface for defects such as cracks, porosity, slag inclusions, and undercut, as well as assessing whether the weld appearance is uniform and smooth, and whether there are weld beads or incomplete welds.

[0004] However, when workers use a magnifying glass to observe welds, some welds are located in poor lighting conditions or contain a lot of welding slag and dust, which can affect their observation. This results in workers needing to carry more auxiliary tools to perform weld appearance inspections, thus affecting work efficiency. Utility Model Content
