20.500.12556/RUL-148725 Vpliv avtomatizacije varjenja nizko serijskega izdelka na donosnost Impact of welding automation on the profitability of a low-volume product Namen diplomske naloge je optimizacija obstoječega delovnega mesta sestave in varjenja izdelka in s tem zmanjšanja stroškov, povečanja produktivnosti in dobičkonosnosti, ter kakovosti izdelave varjencev. Obstoječemu delovnemu mestu smo poiskali tri variante optimizacije procesa s pomočjo avtomatizacije in robotizacije, ter jih podrobno predstavili. Pri optimiziranju delovnega mesta se je izkazalo, da so ključni parametri, ki vplivajo na dvig stroškov delovna sila, prostor, investicija in orodja delovnega mesta. Ugotovili smo, da je ob povečanju letnih količin zaradi parne izdelave pol avtomatiziran proces 1 najbolj rentabilen. S prehodom na novo linijo smo stroške tako znižali za 6,31 %€ na izdelan zvarjenec v primeru parne izdelave. Izračunali smo točko preloma, ki znaša 886 letnih posameznih izdelkov in 435 izdelkov letno v primeru izdelave v paru za pol avtomatiziran proces 1, kar je najboljše med vsemi avtomatiziranimi procesi. The aim of the thesis is to optimise the existing workplace for product assembly and welding, thereby reducing costs, increasing productivity and profitability, and improving the quality of the weldments. For the existing workplace, three process optimisation options were identified through automation and robotization and presented in detail. When optimising the workplace, it turned out that the key parameters influencing the cost increase were labour, space, and workplace tools. We found that with the increase in annual volumes due to steam manufacturing, semi-automated process 1 is the most cost-effective. By switching to the new line, we have thus reduced costs by 6,31 % per per welded part produced in the case of steam production. We have calculated a breaking point of 886 annual individual products and 435 annual products in the case of steam production for semi-automated process 1, which is the best among all automated processes. optimizacija varjenje stroški avtomatizacija postavitev procesa donosnost optimisation welding costs automation process layout profitability true false false [G.
