Strategy and approach towards application of self-optimization in complex gas-metal arc welding processes

The application of self-optimization allows future manufacturing processes to adapt to changing process boundary conditions automatically. Integrated intelligence in the form of expert knowledge allows the extension of application fields of the manufacturing processes, the guarantee of the product quality and the reduction of machine down time. The subject of this paper is research work about the use of self-optimization for the extension of present control strategies; moreover, the approach towards the implementation of self-optimization with regard to gas-metal arc welding processes is referred to.
