Abstract: A method and an apparatus of identifying welding seams of a welding object. The method includes identifying intersection lines between geometrical bodies of the welding object in a three-dimensional model for the welding object, based on geometry of the geometrical bodies to form a collection of welding seams for the welding object. The method also includes eliminating hidden seams from the collection of welding seams for the welding object based on overlapping relationship among the welding seams to form a candidate seam list. Welding seams can be identified automatically and efficiently, and the method or the apparatus makes the automatic programming of the welding robot possible and thus facilitates use of a robot in welding huge and complex structures manufactured in a small batch.

Abstract: Embodiments of the present disclosure relate to a method and apparatus of scheduling welding operations. In an embodiment of the present disclosure, the method includes identifying seams on a welding object in a three-dimensional model for the welding object based on geometry of bodies contained in the welding object. The method also includes determining a welding sequence based on the seams, welding parameters and welding process requirements. The method further includes generating an operation procedure for a welding robot based on another three-dimensional model for the welding robot, the welding sequence, robot path parameters and the welding parameters to schedule the welding operations of the welding object. With embodiments of the present disclosure, the welding procedure could be generated in an automatic way and thus a robot can be used in welding huge and complex structures or structures manufactured in a small batch so that the automatic level can be increased remarkably and the production cost can be reduced accordingly.
