It is thinned.This method cost is high, and detection device is big, and caused ray Radiation On Human body injury is very big, and the detection to micro-crack is sensitive
Spend low.
Changed when ultrasonic Detection Method is propagated using ultrasonic wave in weldment by material acoustics feature and interior tissue
Influence, by the influence degree and status analysis of ultrasonic wave, detect material property and structure change;The method is to operating personnel's
It is required that higher, the defects of distinguishing variety classes difficulty it is larger, need couplant during detection.
Detection method of eddy is based on electromagnetic induction principle, and the magnetic field of change produces vortex in superconductor, if deposited in workpiece
Defect, be mingled with, conductivity variations or structure change can influence the flowing of vortex, superposition magnetic field is changed, according to magnetic field
Change can determine whether welding the defects of.But the method is only suitable for conductive material surface and near surface detection, it is difficult to judges defect
Species, shapes and sizes.
