Objective The aim of the project is to develop a system to provide real time control of the laser welding process of metals using simultaneous multichannel analysis of the plasma plume generated at the interaction point between CO2 laser beam and workpiece. The aim of the research was to develop a system to provide real time control of the laser welding process of metals using simultaneous multichannel analysis of the plasma plume generated at the interaction point between carbon dioxide laser beam and workpiece.The achievements so far are:measurements with different metals, thickness parameters, laser power variation between 1.2 and 5.8 kW have been performed;special analysis and processing software with a parameter library have been developed;identification of significant parameters during welding for process control have been achieved;prototype system development is almost completed to allow monitoring and alarm operation during welding.Engineering of the developed prototype is needed before the system can be exploited.Applications operated with or without success in the following areas:invisible cutting of composites by YAG lasers can be controlled;waste materials can be sorted using YAG laser influenced fluorescence;remote control of petrochemical waste handling (flame control, etc);highly compley alloys treated by laser machining can be handled and controled remotely using plasma analysis;for simple metal laser welding applications this system is too complex and too expensive.The research will develop by : - analysis of the plasma generated during the welding process and collection of the spectra generated by optimized welding processes. - development of an autofocus system. - development of an on-line monitoring and alarm system. - building complete prototype testing system.
