Abstract: Disclosed is a system having a robotic welding system, a controller, a camera, and a processor. The robotic welding system is configured to weld metal sections together in accordance with a plurality of welding variables. The controller is configured to automatically control the robotic welding system. The camera captures sequential images of the welding performed by the robotic welding system. According to an embodiment, the processor is configured to process the sequential images to determine when a selected welding state is to change to a next welding state based on the selected welding state and multiple consistent determinations of the next welding state, and to signal that change to the controller to effect a change in how the welding is performed by the robotic welding system. By considering multiple consistent determinations of the next welding state, there can be a high probability that the next welding state is correct.

Abstract: A presente invenção trata um método que utiliza visão computacional para obter a imagem de um chanfro em V de uma chapa com espessura conhecida. Obtém-se uma imagem do chanfro inicial por meio de câmeras. Com a análise das imagens geradas, é possível obter as dimensões das aberturas inferior e superior do chanfro em V e calcular o volume teórico de material para as n camadas a serem depositadas. Partindo da eficiência de deposição do processo de soldagem para cada camada, o processo utiliza um robô que utiliza o parâmetro velocidade de soldagem para corrigir o volume de material depositado. O método é capaz de fazer correções no volume de material depositado, utilizando a velocidade de soldagem, devido às distorções causadas pelo processo de deposição de material dos sucessivos passes.

Abstract: A method for automatic welding of a structural steel assembly comprising workpieces such as profiles and/or a sheet material. The method comprises using an automated process to receive information from a CAD-CAM program about welds for welding the structural steel assembly, and to post-process the information received from the CAD-CAM program. The information of each single weld received from the CAD-CAM program comprises data about e.g a type of a workpiece or of workpieces of the structural steel assembly which bound the weld, a weld type, a position of the respective weld relative to the workpieces of the structural steel assembly that bound the weld, a shape of the weld, a length of the weld, a path of the weld and a width of the weld. The post-processing comprises splitting each weld in sections of which the individual welding parameters are predefined.
