TOFD detector
HS 810 Portable TOFD Testing Equipment - The Ultimate Weld Inspection Solution
The HS 810 Portable TOFD Testing Equipment is an ASME Certified TOFD Testing Machine that revolutionizes weld integrity assessment. Combining advanced TOFD technology with phased array capabilities, this TOFD Detector with Phased Array delivers unparalleled defect detection for critical pipeline and pressure vessel inspections.
HS 810 Portable TOFD Testing Equipment is developed based on the ultrasonic diffraction time-of-flight method. It is the main instrument for qualification certification (TOFD worker qualification training and assessment prototype for special industries). The Portable TOFD Testing Equipment instrument supports 3 pairs of TOFD flaw detection channels and can be configured with 3 pairs of TOFD probes (expandable). It supports one-time full coverage scanning of workpieces with a thickness of 12mm-200mm. The detection rate of defects in the middle of flat plates or butt welds is extremely high, defects with poor directionality are also easy to detect, and defects extending to the surface can be identified.
Integrates A-scan, B-scan imaging, TOFD imaging, guided wave imaging and other functions
Unique synthetic aperture focusing (SAFT) technology
Built-in on-site inspection process model, automatically generates inspection process
Portable scanner and automatic scanning device replace manual scanning to meet various workpiece inspection requirements
A-scan: RF display improves the instrument's ability to evaluate defect patterns in materials
B-scan imaging: Real-time display of defect cross-sectional shape
TOFD scanning imaging: Real-time display of defect grayscale scanning
Figure, intuitively display defects and evaluate defect quality
Multi-channel TOFD detection and PE detection fully cover partition scanning within 200mm thickness, expandable to 400mm thickness
Through wave removal: Special processing tool for near-surface defects to improve the accuracy of near-surface defect analysis
Horizontal and vertical adjustment: to meet different on-site operating habits
SAFT: internationally recognized function to effectively improve defect measurement accuracy
Instrument software: has both SAFT (synthetic aperture focusing) function and differential through-wave straightening function
Offline analysis software: has SAFT (synthetic aperture focusing) processing function, has the same-screen comparison display function before and after image processing, and has the function of directly converting TOFD images into BMP bitmaps
Offline image analysis: restore and replay the A-scan waveform recorded during scanning; statistical analysis of defect size and contour thickness/amplitude data; record conversion to ASCI/MSWOrd/MS Excel format report
