By constructing a neural network based on PPO and using the reference image block and the image block to be detected as the dual-channel input of the network, the method predicts the translation relation between the two images and corrects the location of feature points in the weld image. The localization accuracy estimation network (LAE-Net) is built to update the reference image block during the welding process, which is helpful to reduce the tracking error.
Off-line simulation results show that the proposed algorithm has strong robustness and performs well on the test set of curved seam images with strong noise. In the welding experiment, the movement of welding torch is stable, the molten material is uniform and smooth and the welding error is small, which can meet the requirements of industrial production.
The idea of image registration is applied to weld seam tracking, and the weld seam tracking network is built on the basis of PPO. In order to further improve the tracking accuracy, the LAE-Net is constructed and the reference images can be updated.
Arc welding is the process of joining metals using the heat generated from an electric arc, and this can be done using different techniques such as MIG (Gas Metal Arc Welding), TIG (Gas Tungsten Arc Welding), PAW (Plasma Arc Welding) and more. It is a go-to method for anyone working with metal, whether in the automotive industry, construction or industrial equipment manufacturing.
One of the major challenges today is the shortage of skilled welders; the American Welding Society (AWS) projects that 330,000 new welding professionals are needed by with 82,500 average welding jobs to be filled annually between and in the United States to meet the increasing demands from industry sectors such as infrastructure, energy, automotive and construction.
Now combine that with rising and constantly fluctuating material costs, supply chain disruptions and the need for customization and part flexibility, and it comes as no surprise that keeping production costs down and profit margins up is a major challenge.
Technological advancements—such as automation and advanced manufacturing processes—are needed in order to stay competitive. However, navigating this landscape can feel daunting, considering it requires time, investment and training.
