In the field of welding, the concern with ergonomic and usability factors due to the increasing incorporation of computer technologies and the consequent transformation of the activities performed by welders. Therefore, the objective of this study was to evaluate the usability of an interactive system for the robotic welding by applying methods and techniques of usability engineering. So were performed in the laboratory tests of interaction with the equipment in a specially constructed bench to simulate typical activities involving the configuration parameters and welding processes. The survey sample consisted of thirteen participants involved in welding research. To collect data specific questionnaires were used to assess participants' satisfaction with the usability of the system. Yet, to evaluate the performance of participants during the tasks were recorded times and completion rates. Thus, it was found that the interactive system met or exceeded the expectations of users regarding the usefulness, ease of use, ease of learning and quality of the interface. Finally, the usability evaluation has provided a diagnosis of the factors that represent obstacles for users, and information that may be used in improving future versions of the equipment.
