Robots in the Industry 4.0

The collaborative robots applications are widely increasing in the industrial application. In the welding process, the robot application area is continuously growing. The manual welding is a professional but really hard physical work, the replacing by collaborative robots will be a big advance for the industry. The collaborative robots application in the welding tasks is not solved yet. In this article, the authors want to analyze by risk assessment the dangers for the human in the welding workplace. On the base of the results determines the danger zones of the collaborative welder robot workplace on the base of the dangers level and kind. Also in this applicability analysis, the authors count the requirable sensors for the collaborative welder robot in the welding to assure labor safety. On the base of the labor safety requirements the aim of this work to establish a technical aspect system to found the launch of the collaborative robot welding for the industrial application.
