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.
