Computer aided programming in offline programming systems of welding robots

An approach by interfacing a feature modeler of welded structure and an arc welding expert system to provide the automatic generation of welding paths and the corresponding technology data was proposed.The prototype system was developed in SolidWorks.An arc welding expert system can automatically generate welding process parameters.Its input data came from the feature modeler of welding part.It combined case-based reasoning with artificial neural networks methods to deal with the welding process design.Several network modules were developed to learn from welding process database based on back-propagation neural networks.
