50/64/128 element wheel probes
•Low attenuation transparent tire
•Excellent acoustic impedance
•Portable immersion system
Special TKY welding
In this case, welding could only be covered by seconded leg due to unique geometric.
This would cause complex echo indications. Doppler Phascan can display the CAD couture drawing of specimen for quick
and easy echo identifying.
Automobile gears
Gear in this case has limited probe access and has a special welding. Doppler customized a compact wedge to mount
on probe reversely(supported by Phascan ) .
Power system aluminum clamp
• Doppler’s flexible probe could couple
against variety of waved inspected
surface.
• 3mm slim height leads to good
accessibility
FSW (Friction stir welding)
• Doppler has well experienced
on providing equipment for
FSW welding inspection.
4mm aircraft FSW plate
High temperature tightening bolt of power station
• These bolts made of coarse grain
austenitic material, more
attenuation, lower amplitudes.
• Threads and relief groove and
other reflectors on bolt may it
difficult to identify the flaw echo.
• Doppler’s high quality probe and
transmission receiving PA unit,
make the inspection easier.
Drill Pipe
• Cracks are the common flaw to the drill pipe, transverse
or longitudinal.
• Phased array can detect and size the flaws much easier
than conventional UT.
Thermal power station U tube oxide deposition
Busted tube Damaged turbine blades
RT has limited access, and radiation hazard
Doppler has customized a specialized loop PAUT probe
And phased array system
To detect the height of oxide deposition in U tubes.
Wind power bolt guided wave inspection
• CGWT(Cylindrically Guided Wave Technique)
generated by specialized PAUT system which is
designed and made by Doppler .
• The system customizing includes probe, PA unit, PA
software No cracks

Linear : normal weld
DL = dual linear : SUS cor grain
Coarse-grained materials or systems have fewer, larger discrete components (grain ใหญ่) จะเกิด scattering จึงต้องใช้ DL เพื่อให้รับสัญญาณได้ดีขึ้น
Element Internal focus ได้ resolution ดีกว่า
First digit is frequency
Higher frequency for thin material 5-10 mm
Element no.. Is not related to thickness
