The welding program optimization of a S355 steel assembly used in agricultural machinery

Abstract

The paper will include the realization of a weld joint line with an ABB robot. The manufacturing area contains a welding device and a robot. For the robotic welding, the methods and a complete welding program will be presented. The first stage is the design of the device that can be used for manufacturing a range of comparable size pieces with similar gripping capability. There are described the axes and the way of movement, the presentation of the speeds for the rotating joints and roto-translation. CAD design of the workpiece including WPS (welding technology that contains the shape of each joint and welding parameters: welding current, electric arc voltage, welding speed and secondary parameters). The base material, the addition material, protective gases and a list of parts from the robot that require periodic changes will be presented. It is presented the CAD design of the workpiece including WPS.
