There are three types of burners, one small type, two medium types and one big type. Each consists of aluminium body, nozzle, ignition electrode and gas leakage protection fuse. Prior to construction itself,  variant solutions of the assembly operations arrangement are designated. From those, the most appropriate one is chosen based on multicriteria weighting method. Construction of assembly line is created using 3D modelling program with necessary design calculations. For selected assemblies and parts, a drawing documentation has been created. Risk analysis and security of the machine’s normal operation is an integral part of the thesis. Risk analysis is created for the machine’s normal operation. In conclusion, the costs of purchasing the assembly line are calculated and the return of the investment for purchasing the machine is assessed.
