Abstract
A weld scanner for a real-life bridge and scanning method thereof is disclosed. The weld scanner includes a running portion and a scanning portion mounted on a scanner chassis. A front end and a tail end of the scanner chassis are both provided with a laser range finder. A magnet is arranged at a bottom portion of the scanner chassis. The scanning portion includes a probe slider, a bendable metal pipe and a probe connected in sequence. A gear is arranged on the probe slider, and the gear is meshed with a rack inside a scanner chassis chute. The weld scanner scans while the running portion moves forward along a weld, and scans a suspected defect position more carefully when a magnetic field change is detected.
