Document Type and Number:
Japanese Patent JP2003512935
Kind Code:
A
Abstract:
A method and apparatus for monitoring quality of a weld bead during a welding process utilizing an electronic controller is disclosed. The method and apparatus includes determining an average power spectral density value for a first welding parameter signal between a first predetermined frequency and a second predetermined frequency, determining an average power spectral density value for a second welding parameter signal between a first predetermined frequency and a second predetermined frequency, and comparing the average power spectral density value for the second welding parameter signal with the average power spectral density value for the first welding parameter signal and terminating the welding process if the average power spectral density value for the first welding parameter signal exceeds the average power spectral density value for the second welding parameter signal.
