VIRTUAL TECHNOLOGICAL EXPERIMENT IN WELDING

Objective

The objective of VITEWE is to develop a method that allows the optimisation of welding parameters using a virtual reality procedure before the execution of the actual welding. This method will be based on sophisticated mathematical models, advanced methods of numerical simulations, a specially created database concerning welding technologies and equipment, and an advanced virtual reality graphical representation of the welding.

The virtual welding experiment will be organised as follows:
the user will choose the basic welding technology to be used (laser, plasma-arc, electron beam, etc.), the required set up, materials to be welded, and the welding parameters (speed, power, energy beam diameter);
based on the chosen welding conditions, a virtual experiment will be executed numerically; the evolution of the welding process will be represented by the dynamics of: temperature fields, molten pool shape, keyhole formation, etc.;
the whole virtual experiment will be analysed by a virtual diagnostic equipment such as pyrometers, acoustic emission, thermocouples, spectrometers, etc.;
the result of the virtual experiment will be represented by a 3D image of the obtained welded seam and its cross-sections;
the results of the virtual welding will be analysed and necessary modifications of the parameters will take place before the next virtual welding.
