For steel plates with a large area, if the current handheld equipment is used for gradual detection, it will take a lot of time and cause great fatigue to the operator. And currently, the detection path of the detection surface is manually controlled, resulting in situations such as repeated detection and missed detection, and there are phenomena of incomplete and inaccurate detection results, making the reliability of the detection results of steel products insufficient. Therefore, we redesigned a handheld flaw detection device for 7Ni steel plates. Summary of the Utility Model
