DIGITAL MICROSCOPE
Evident’s DSX2000 is a fully motorized
digital microscope aimed at simplifying
material analysis and inspection work-
flows. The system integrates imaging,
measurement, analysis, and reporting, with
high-resolution imaging from macro to
micro levels, with capabilities beyond 4K.
The DSX2000 is designed to stream-
line tasks for researchers, failure analysis
engineers, and QC lab professionals. It
features automatic objective switching
through a motorized zoom head and
revolving nosepiece, and users can
quickly access seven different observa-
tion methods to find optimal viewing
conditions. The new shaded relief
method allows for the detection of fine
defects in real time. When paired with
Evident’s PRECiV™ image analysis soft-
ware, the DSX2000 offers additional
workflow improvements.

NEW GUIDELINE ON
AIR-COUPLED UT
The German Society for Non-Destructive
Testing (DGZfP) has released the “ACUT
Guideline: A Guide to Performing
Air-Coupled Ultrasonic Testing.”
Developed by the DGZfP Ultrasonic Testing
Committee’s subcommittee on air-coupled
ultrasonic testing (ACUT), the guideline
offers a comprehensive introduction to
noncontact ultrasonic testing. Martin Fuchs,
a development engineer at SONOTEC
GmbH, played a key role in its creation.
Available for free download since January
2025, the document covers essential
topics such as the fundamentals of ACUT,
testing system requirements, methods,
application areas, and data evaluation.
ACUT utilizes ultrasound waves trans-
mitted through air, making it ideal for
inspecting sensitive, porous, or hard-to-
reach materials like composites, wood,
foams, and ceramics. Fuchs emphasized
that the guideline aims to enhance ACUT
adoption and optimize testing processes,
particularly where traditional contact-
based methods are not suitable.

NDT VIDEO ON
ASSESSING CONCRETE
CEV Group, the Council of Engineers and
Valuers Group based in India, released
an 80-minute video to equip valuation
professionals with the skills needed to
assess concrete structures using NDT.
This video focuses on NDT techniques
for evaluating the integrity and durability
of concrete, a critical aspect of property
valuation.
The video covers key NDT methods
such as ultrasonic pulse velocity, rebound
hammer testing, and core sampling,
explaining how each method assesses
concrete’s strength and condition. It’s a
valuable resource for valuation aspirants
and professionals looking to integrate
NDT into their assessments.

ANSI/AWS A3.0M/A3.0-2025: STANDARD
WELDING TERMS AND DEFINITIONS
The March 2025 release of ANSI/AWS
A3.0M/A3.0-2025, Standard Welding
Terms and Definitions Including Terms
for Additive Manufacturing, Adhesive
Bonding, Brazing, Soldering, Thermal
Cutting, Thermal Spraying, and
Nondestructive Examination, issued by
the American Welding Society (AWS),
reaffirms the foundational role of precise
terminology in welding and joining
disciplines. As the welding industry
continues to evolve with the integration
of advanced technologies and diver-
sified applications, a clear and unified
language becomes essential for effec-
tive communication, quality assurance,
and international standardization. This
updated edition, compiled with input
from a broad range of industry profes-
sionals, educators, and researchers,
solidifies ANSI/AWS A3.0 as the definitive
reference for welding-related definitions,
symbols, and concepts.
Welding operations span virtually
every major sector—from aerospace and
automotive to energy, construction, and
shipbuilding. In each of these fields, accu-
rate and consistent terminology is critical
to maintaining clarity between designers,
engineers, inspectors, technicians, and
regulatory authorities. For example,
understanding the difference between
a “weld pass” and a “weld bead,” or
the nuances between “fusion welding”
and “pressure welding,” can have major
implications for procedure qualification,
inspection criteria, and product perfor-
mance. Misinterpretation of such terms
can lead to costly errors, nonconfor-
mance, or safety hazards.
The 2025 revision of ANSI/AWS
A3.0M/A3.0 includes newly introduced
terms that reflect the rapid technological
growth in the field, particularly in areas
like robotic and laser welding, additive
manufacturing, and advanced nonde-
structive testing. Furthermore, the stan-
dard refines and reorganizes existing
definitions to better support the devel-
opment of welder training programs and
industry documentation. It also ensures
compatibility with other AWS codes and
international standards, fostering global
interoperability in welding practices.
Beyond its technical scope, ANSI/AWS
A3.0M/A3.0-2025 plays a strategic role
in harmonizing communication across a
growingly interconnected supply chain.
As fabrication becomes more global-
ized, the ability to reference standardized
terminology is invaluable for project coor-
dination, contract clarity, and regulatory
compliance.
With this latest edition, AWS continues
to champion clarity and precision in
welding, ensuring that industry profes-
sionals worldwide are aligned in both
language and intent. ANSI/AWS A3.0M/
A3.0-2025 remains not just a glossary of
terms, but a vital tool for building safer,
stronger, and more reliable welded
structures.
