Acoustic-emission inspection of flaws during laser bonding of articles made of VT20 titanium alloy
Source abstract
Abstract
The acoustic-emission method for inspecting flaws that form during laser bonding with the use of a CO2 continuous-wave laser with a power of up to 8 kW and characteristics that can be preadjusted prior to welding is considered. The structure of acoustic-emission signals registered in a specimen’s flawed domain has been analyzed using the wavelet transform. It has been shown that the structural coefficients of the acoustic-emission signals localized in specimen’s flawed sections become identical over time.
