Information : Laser Spot Weld Representation
Although current CAD systems model part geometry very well, they are limited in their ability to model assemblies and the "liaisons" between components. Sandia National Laboratories (SNL) has extended their design system to represent one type of liaison information between components, specifically welds. The laser spot weld is a simple part-to-part relationship that can be modeled; information and extensions include which parts to join, geometry such as points and curves, design parameters such as depth and diameter, manufacturing parameters such as power and aperture, and modeler interactions such as what data must survive editing operations.
Extensions include both representing weld information and providing access to weld data for the robotic assembly planning module used in the A-PRIMED project. Current work is focused on expanding this capability to support fastening operations such as gluing. Enhanced design capture, better sharing of design information, management of legacy data, and enabling automation through other software systems such as robotic assembly planning are all benefits derived from this capability.
