| Abstract: | The static waveforms of the friction stir welded(FSW) joint defects were obtained by single-crystal angle probe and double-crystal angle probe testing.The relationship between the form of the defects and the static waveform was studied,and the results by single-crystal angle probe testing and double-crystal probe testing was compared.The results indicate that the static waveforms by single-crystal angle probe testing and double-crystal probe testing are similar.The shape and size of the defects directly inf... |
