Title: Method for monitoring quality of laser beam welding part and its device
Inventor: MORI YOICHI
IPC: B23K26/21
Filed: 2002-05-02
Abstract: <P>PROBLEM TO BE SOLVED: To judge welding quality such as porosity, an underfill, and unwelding with high accuracy without increasing the processing burden of a CPU.  <P>SOLUTION: A welding part of a workpiece is irradiated with a laser beam by a YAG laser. A reflected beam from the welding part irradiated with the laser beam is detected. The detected reflected beam is converted to an electrical signal. Changes with the elapse of time of the converted electrical signal is stored. An FFT waveform of the electrical signal is calculated on the basis of the changes with the elapse of time of the electrical signal. The sum f (α) of signal strength in frequency band (α) and the sum f (β) of the signal strength in the frequency band (β) are calculated on the basis of the calculated FFT waveform. A crossing point of a straight line X=f (α) and Y=f (β) is obtained by respectively plotting the sums f (α) and f (β) of the respective signal strength to an X axis and a Y axis constituting a two-dimensional coordinate system. The quality of the obtained crossing point is specified on the basis of the inspection result of the quality of the welding part of the workpiece welded by the YAG laser. Regions of the quality by type (an article having excellent quality, the porosity, the underfill, and the unwelding) are prepared in the two-dimensional coordinate system by repeating the steps up to the aforementioned steps.  <P>COPYRIGHT: (C)2004,JPO
