  28. PART 3 Typical Applications
  29. Applications Phascan Phased array unit Analyze software Pattern plan software scanners PA Probe/wedge Accessories
  30. Variety Scans Phascan/Flexscan+ ENC-10 + Varity of Probes/wedges •ENC-10, Low profiled encoder •Low cost solution •Limited access inspection
  31. Small piping welding inspection Phascan+ CRS-1/CRS-2 SANNER+ D10 PROBE/WEDGE •4th Gen unique design, robust and reliable •Pipe diameter: 0.8”(20mm) ~4.5”(114.3mm). •Focused probe crystal, ideal for piping convex. •Tool free chain assembly(optional).
  32. Welding, Corrosion, Aerospace, Base metal universal scans • Widely applicable. • PA + ToFD Simultaneous scan • Highly compact and portable. • Modular design, easily transform. Phascan/Flexscan+ Mos-01 / Mos-02 / Mos-03 / Mos-04 Varity of Probes/wedges
  33. Welding, Corrosion, Aerospace, Base metal universal scans Phascan/Flexscan+ Mos-01 / Mos-02 / Mos-03 / Mos-04 Varity of Probes/wedges • Diameter: 6”(152mm) to 21.5’’(550mm) • PA/UT+ToFD simultaneous scan • Steady scan and coupling
  34. Plates, pipes welding PA+TOFD inspection Phascan/Flexscan+ FC-01 or FC-02 scanner + ToFD probes/wedges+ D1/D2 PA probes/wedges •Diameter: 6”(152mm) to greater •PA/UT+ToFD simultaneous scan. •Brake device, Convex/Concave(FC-02) FC-02 FC-01
  35. Corrosion, Aerospace, Base metal Phascan/Flexscan + 50/64/128 element wheel probes •Low attenuation transparent tire •Excellent acoustic impedance •Portable immersion system
  36. 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.
  37. 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 ) .
  38. Power system aluminum clamp • Doppler’s flexible probe could couple against variety of waved inspected surface. • 3mm slim height leads to good accessibility
  39. FSW (Friction stir welding) • Doppler has well experienced on providing equipment for FSW welding inspection. 4mm aircraft FSW plate
  40. Turbine blade root Groove Type Straddle Type
  41. T root of turbine blades
  42. 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.
  43. 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.
  44. 大管 CFRP composite plate 1.78mm thickness 2.21mm thickness
  45. 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.
  46. 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 With Cracks
