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.

Summary
The paper will present an optimization of the welding process of steel components S355 used in the construction of agricultural machinery. The welding installation consists of an ABB welding robot and a welding station. The welding station has 3 rotation axes (figure 1, a), it performs a movement around the z-axis which allows access of the two welding posts to the welding torch. The station allows rotation on the x and y axes. The welding station allows the mounting of a welding device (figure 1, b) that is specific to each assembly that could be welded in this area. The robot programming is done with the FlexPendant SDK, Figure 2[1]. The programming of the robot is done by learning, by the tactile sweep of the welding joint not by predetermined coordinates. The coordinates results and are recorded for the following welding commands
