LMT Advanced NDE Solutions
Phased Array Ultrasonic Testing
LMT, a business unit of
Curtiss-Wright, has been
providing NDE services to the
nuclear power industry for
over 30 years.
Our team of experts develop
and deliver the latest
technology, procedures, and
programs to help ensure
continued safe operation,
equipment reliability and
compliance with industry and
regulatory standards.

Fully Encoded Phased Array Ultrasonic Testing provides a cost effective
solution for complex examinations.
Phased Array Ultrasonic Testing (PAUT) is an advanced method of volumetric
examination that can reveal all types of material defects. LMT, a leader in the
delivery of PAUT, has developed several “first use” applications that provide
customers with innovative solutions for technically challenging and critical
situations.
LMT performs PAUT services using their team of highly skilled and
experienced technicians utilizing LMT customized delivery systems.
PAUT: Advanced Volumetric Examination in lieu of Radiography (RT)
LMT has extensive experience in the utilization of their innovative PAUT
technology to confirm material integrity on modification and replacement
projects in lieu of RT. LMT has delivered this PAUT in lieu of radiography in
both B31.1 and ASME Code applications.
PAUT provides significant improvements by:
— Superior flaw discrimination and flaw positioning
— Providing superior mapping for defect removal
— Performing weld examination concurrent with other work activities
— Reducing examination durations
— Eliminating RAD Protection support
— Eliminating work stoppage to perform testing
PAUT: Dissimilar Metal Nozzle Welds
LMT delivered “first use” applications for PAUT of PWR Reactor Pressure
Vessel (RPV) Dissimilar Metal (DM) nozzle welds and RCS piping nozzle
DM welds. LMT first performed RPV nozzle DM weld examinations on
Westinghouse RPV nozzles eliminating the need to remove the core barrel.
This application significantly reduced the critical path duration while removing
the radiological risk. Encoded PAUT has also been delivered for RCS
component (SG, RCP, drains, attachment welds) DM welds. LMT delivers the
same PAUT techniques for the examination of BWR vessel nozzle welds. All
testing meets ASME Code Section XI Appendix VIII.

PAUT: Socket-Welded Joints
LMT has developed a “first use” application for PAUT in lieu of RT
or destructive testing for socket-welded joint examination. Nuclear
power plants require the examination of Socket-Welded Joints as
part of their plant life extension (PLEX) programs. By delivering PAUT
for this application, LMT provides utilities with improvements in
ALARA, schedule duration and cost, all without the schedule impact
associated with RT.
Large Bore Delivery System
LMT is committed to the advancement of PAUT technology by
sponsoring and conducting periodic Phased Array UT Workshops.
