Towards a digital twin for manufacturing processes: applicability on laser welding

Optimization and control of Manufacturing Processes seem to be the key-enabling approaches towards Efficient Manufacturing and Zero-defect. Thus, it is of high importance to study what-if scenarios regarding changes of Process Parameters. To achieve this in real time, Digital Twins have to be designed and implemented. Towards this end, in the current work, a specific methodology, originating from process physics is reviewed as a candidate technology for the process level Digital Twin. The requirements are stated and checked one-to-one and respective numerical results are shown. Discussion on Zero-defect and optimization under the prism of Industry 4.0 is presented
