Through this master's thesis "Creating a manufacturing process for production bottom side of container" the technology is shown, the most commonly used tools, machines, materials and procedures in the manufacture bottom side of container type 20-1CC. In the first chapter, the definition of containers is given and the requirements that container need to meet. Also different types off containers is shown which we using today and their way of marking. How today the most containers are using for transport goods by sea, the operating conditions in this mode of transport are described. The second shapter describes the 20-1CC container in more detail. The standards and redulations that 20-1CC container must meet ate presented. Also materials which most commonly used for certain parts of the container are given. In the third chapter the manufacturing process for bottom side of container 20-1CC production is shown. The processing procedures used and all the technical equipment required are explained and listed. Also all welded joints between all parts are shown. The relationship pg welding costs is presented at the end of this chapter. The fourth chapter presents two robotic systems for welding certain parts of bottom side of container. Two examples of robotic welding are given. In the first example, the gusset are welded to the cross member with robot and in the second example, the lower plates of pockets are welded with four robots. At the end of this paper the conclusion is given.
