PALM Flat Scannerfor general weld inspection

Weld inspections are crucial during the manufacturing process, as well as
on a regular basis to ensure weld integrity. Inspections with conventional
ultrasonic angle beam probes are time consuming and provide limited
documentation. Probability of detection is reduced due to the limited
amount of angles used, which could result in missed indications. Waygate
Technologies now offers the PALM Flat Scanner to perform more accurate
and efficient weld inspections.

PALM Flat Scanner
Encoded Phased-Array inspection of welds offers the benefitsof a reduced inspection time, while increasing the probabilityof detection and providing a comprehensive documentationof the inspection results directly on the instrument. ThePALM Flat Scanner is a versatile and ergonomic inspection
tool featuring an integrated encoder and magnetic wheels,
allowing vertical and overhead operation. The scanner canbe used on diameters larger than 90 mm for circumferential
scanning and 200 mm for axial scanning.

Features• Compact, rigid, lightweight and robust (IP67, stainless)• Low profile to pass clearances as low as 30 mm (1.2”)
dependent on probe• Reproducible adjustment of the probe position based on
an integrated ruler• Adaptive to various probes and wedges• Integrated robust encoder, which can easily be replacedby the operator• Spring-loading and gimbaling of probes• Magnetic wheels to stick to tube and for straight guiding• Manual brake for hand-free locking at any position• Easy switching from axial to circumferential direction
and back• Operable by a single person• Easy to set up• CE compliant

2Operating information
The PALM Flat Scanner– part of the PALM Scanner family circumferentially inspects pipes of diameters from 90 mm(3.5”) outer diameter to flat and inner diameters down to250 mm (10”), The minimum diameter of axial scanning is200 mm. The tools can carry probes up to the size of 70 mm(length) x 50 mm (width) to suit any inspection procedureregardless of tube thickness, material or acceptance criteria.
The PALM Flat Scanner is delivered with a wide selection ofaccessories in order to make inspection and/or equipment
handling even simpler. With other types of probes, the PALM
Flat Scanner has
the potential tosolve many otherapplications as well.

UT scanning results

C-scan of weld displaying indications as high reflection
signals (red and yellow amplitudes). The weld geometry isdisplayed in the C-Scan for localization. Cursors are available
after the scan for determining the position of indications withrespect to the weld geometry.

B-scan of weld displaying the depths of indications. The
double V weld geometry of a 25 mm thick part is shown.
Indications are detected between 1st and 2nd skip in theupper part of the weld at a depth of about 10 mm.

0600185** How to order custom wedge curvatures

Applies only to part numbers 0600183 and 0600220.
Choose letter specifying the curvature geometry according to below pictures.

When placing the order use the curvature specification and radius of thecurvature to specify the wedge.
Example: ordering 0600183 NPA36°M R.. (A-D) in curvature geometry “A”
with 60 mm radius.
Use the following identifier when ordering
0600183		

NPA36°M R60 A
