Abstract

A method (100) and an apparatus (800) of identifying welding seams of a welding object. The method (100) comprises identifying (102) intersection lines between geometrical bodies (221, 222, 223, 224)of the welding object in a three-dimensional model (220) for the welding object, based on geometry of the geometrical bodies (221, 222, 223, 224) to form a collection of welding seams (S1-S16) for thewelding object. The method (100) also comprises eliminating (104) hidden seams (S6',S14') from the collection of welding seams (S1-S16) for the welding object based on overlapping relationship amongthe welding seams (S1-S16) to form a candidate seam list. Welding seams can be identified automatically and efficiently, and the method (100) or the apparatus (800) makes the automatic programming ofthe welding robot possible and thus facilitates use of a robot in welding huge and complex structures or structures manufactured in a small batch.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of welding, and more particularly, to a method and an apparatus for identifying a weld seam of a welding object. Background technique [0002] At present, robots are widely used in many fields such as welding, assembly, conveying, painting, and laser processing. Welding robots can automatically perform welding operations in a predetermined manner according to robot programs. For example, in the shipbuilding industry, small steel ships usually have hundreds of thousands to millions of weld points, which means a huge workload. However, the current level of automation in welding in shipbuilding is still rather low, and a large amount of manpower is required to perform welding operations on board. The main obstacle to using robots in this industry is that robot programming is time-consuming and complex. Therefore, there is a need to provide a solution that facilitates the use of robots ...
