Manual Curved Bed
X-Y Scanner


The vast majority of ultrasonic inspection relies on an operator manually scanning an ultrasonic probe over the surface of the piece and interpreting the signals he sees on a flaw detector. A major disadvantage of this is that no automatically produced permanent record of the inspection is available.

The Phoenix Manual Curved Bed X-Y Scanner when used with any suitable display system enables the operator to obtain such a permanent record when either corrosion mapping or carrying out weld inspection.

Benefits

The unit combines ease and speed of operation with a high degree of accuracy. It will operate on any material and in any position from the horizontal through to the vertical. Curvatures in one plane on concave surfaces can be accommodated down to 600mm diameter and on convex surfaces down to 150mm diameter. Scan dimensions are 500mm in the 'X' direction and infinity in the 'Y' direction.

Construction and Use

SCANNER

The scanner body comprises a standard unit capable of being fitted to three track attachment options via a quick release device. A rigid primary X-axis arm runs through the body of the scanner. This arm is easily replaceable and is available in different lengths.

An automatic incrementing facility is included which operates along the Y-axis. This facility can be switched out to allow a 'Free Scan' capability. When switched in, the increment along the Y-axis is controlled by the movement in the primary X-axis. The pitch of this increment is infinitely variable on a ratio of 3:1. Therefore, for a 500mm X-axis movement the increment in the Y-axis is adjustable between 4mm and 20mm. The scan pattern is of the Raster type. Positional information in both X and Y axes is provided by encoded outputs.

TRACK

Three track attachment options are available:

TRANSDUCER MOUNTING

The ultrasonic transducers are mounted in a toolpost secured to the X-axis arm. The toolpost includes a transducer holder spring loaded onto the surface plate. It has an integral couplant supply if required. The toolpost and holder arrangement has been developed over many years to ensure good transducer contact with the plate surface and a consistent couplant supply.

User Support

Phoenix Inspection Systems is responsible for the design, manufacture and supply of all its equipment. Comprehensive customer support and training is available as a matter of course. In addition, a specialised consultancy service, based on extensive practical experience of N.D.E. systems, can be called upon to advise on specific inspection problems.
