A system for inspecting a weld on a component where the weld has a plurality of cross-sections includes a camera disposed above the weld that optically senses a weld position. A projector disposed above the weld projects on to the component along a length of the weld position a primary scan path with a primary scan path start point and a primary scan path end point. An imaging probe scans the weld as the imaging probe moves from the primary scan path start point to the primary scan path end point to generate a plurality of 2D cross-sectional images of the weld corresponding to the cross-sections of the weld, the imaging probe having a position and skew angle that vary as the imaging probe moves. Each 2D cross-sectional image of the weld is optically encoded with a respective imaging probe position and a respective imaging probe skew angle.

Apparatus and techniques as shown and described herein can be used to provide non-destructive inspection using a scanner assembly that can have one or more arms that can be used to position a probe assembly such that full inspection coverage of a structure can be achieved in a semi-automated or automated manner using as few as a single scanner assembly. Such apparatus and techniques can include a scanner assembly having multiple arms and corresponding probe assemblies, such as can be used to perform acoustic inspection of a longitudinal weld structure.

The invention discloses an ultrasonic testing device for rail bottom and a testing method using the same. Top surfaces of both sides of the rail bottom include at least one working surface respectively, and the working surface is at least provided with one set of phased array probe assemblies. Each set of phased array probe assemblies includes two phased array probes distributed on both sides of a weld seam, and the phased array probe forms a contact area with the working surface and generates pulsed ultrasonic beams with different incident angles to enter the rail bottom for flaw testing. The phased array probe can be deflected relative to the rail bottom to realize full-coverage testing for the rail bottom.
