General Purpose Weld Inspection Manipulator
is a unique automated NDT inspection manipulator. It was originally
developed to inspect welds on boilers at the Sizewell A nuclear
power station. The HT version speeds up process times by allowing
welding, heat treatment and ultrasonic testing to be carried out
at the same time. This is achieved by allowing continuous inspection
at temperatures up to 170ºC.
offers an ambient temperature version of the TRAKIT scanner.

Lightweight flexible modular structure, easily adapted
Probe pans can be replaced with the scanner in position.
HT version operates up to 170ºC
Low profile to avoid pipework, support beams and lagging
Guaranteed full coverage of the weld.
manipulator is designed to fit onto the same Gullco track that
has been used to carry out the welding. As such it can offer any
fabricator a cost effective entry into automatic inspection. If
the HT version is used, ultrasonic scanning can be carried out
whilst the fabrication is still hot, especially important if post
weld heat treatment is required.
For hot scanning
the couplant used is a silicone oil compound whilst the ambient
scans use a water based gel. Couplant collection trays can be
used to collect silicone couplant for re-cycling, giving additional
is designed to fit within a small envelope. The original envelope
was defined by the positions of the horizontal support beams,
vertical pipes and the lagging, which was left in situ. During
the hot scans to reduce heat loss, only a limited area of the
boiler was exposed yet the system had to inspect the maximum length

can be configured to perform axial scans with circumferential
increments or vice versa.
up to 12 probes

Air cooled for hot scans
Fits standard Gullco track
Systems is responsible for the design, manufacturing 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
