Computer platform for the analysis of the process of laser welding

This research project aims at establishing a computer platform especially for the analysis of process of laser welding. After the laser induced plasma photographs, metallographic photographs of the weld are scanned into computer and the welding parameters are input, the results of the analysis can be obtained by means of selecting different function-keys. The main results of analysis include: the solid angle of spatter distribution, the velocity of the unit volume spatter, the area of the weld, the penetration-to-width ratio of the weld, the included angle of side boundary line of the weld, the RGB chart and the grey isothermal chart of plasma and the area of laser welding plasma in the different temperature district and so on.
