Data Process Method for Measurement of Plasma Plume Temperature Field in Deep Penetration Laser Welding

Chen Genyu Zhao Zhi Zhang Yi Zhang Jun(State Key Laboratory of Advanced Design and Manufacturing for Vehicle Body,Hunan University,Changsha,Hunan 410082,China)  
The temperature field of laser-induced plasma in laser welding is hard to be obtained by the spectral analysis method.By using fast Fourier transform(FFT) and Hankel inversion algorithms,a data processing method based on Abel inversion for measuring temperature distribution of plasma is studied.Meanwhile the precision in the process of the dada is analyzed.The standard error e was about 3.23×10-2 at the number of dispersed points N of 41.The results show that the data process method can be very useful in the observation of the temperature filed of laser-induced plasma by using a multi-channel spectral analyzer.The temperature of plasma plume in the center area of laser beam appeared to be higher than the area near the laser beam.
