Arc welding is an indirectly controlled process where the electrical variables of arc are
controlled to create joints of requisite mechanical and metallurgical characteristics after …

The Pole Placement Control is a control strategy to reallocate poles of a system forcing a
desired behaviour to it. The technique is established on states feedback backed by a gain …

Welding processes have relevant importance in many areas of industry, especially in the
manufacturing area. The choice of mass transfer mode, to weld metal plates, depends on …

Gas metal arc welding (GMAW) is currently the most widely used arc welding processes in
the industry because of its high metal deposition rate, flexibility and low cost. It is attractive …

Using the welding current and voltage signal processing, we have studied the influence that
the diameter of the welding wire to the welding quality detection. For the experiments, We …

During the robotic arc welding process, not only the images taken are often unclear, but also
the features are not obvious due to the interference of arc, splash and smoke. Therefore, it is …

In this study, we developed PC software and the monitoring system to evaluate welding
quality by measuring the Arc welding voltage and current. The developed program …
