Description

Technical Field

[0001] The present invention relates to the technical field of welding surface detection equipment, and in particular to an intelligent detection device for welding surface defects. Background Art

[0002] Metal plates are flat rectangular building material plates made of standard sizes. Steel plates are welded into the required size as needed. After welding, the weld surface is inspected mainly by visual inspection. Inspectors inspect the plates visually under incandescent lamps. Most of the inspection process relies on the inspectors' vision and experience to evaluate. This manual inspection method not only has large inspection errors but is also easily affected by personal factors. The inspection standards of different inspectors are often inconsistent, which will cause the inspection results to vary from person to person. Over-inspection and missed inspection are difficult to avoid, resulting in uneven surface quality of the plates.
