Abstract
Optimizacija procesov v industriji je ključna za konkurenčnost, pri čemer ima pomembno vlogo uporaba laserjev. Nerjavno jeklo, zaradi svoje korozijske odpornosti, pogosto potrebuje obdelavo po varjenju, saj varjenje poškoduje zaščitno oksidno plast. Namen naloge je bil raziskati možnost optimizacije procesa varjenja in čiščenja zvara nerjavnega jekla z uporabo kontinuirnega laserja. Spreminjali smo parametre čiščenja, kot so oddaljenost od gorišča laserskega snopa, moč in hitrost skeniranja. Rezultate smo vizualno ocenili in postavili v matriko. Ugotovili smo, da zaradi prevelikega vnosa toplote, površina ni le očiščena, pač pa tudi delno pretaljena.

Title:Laser cleaning of welds made on stainless steel AISI 304
Abstract:
Optimization of processes in industry is crucial for competitiveness, with lasers playing an important role. Stainless steel, due to its corrosion resistance, often requires treatment after welding, as welding damages the protective oxide layer. The aim of this thesis was to explore the possibility of optimizing the welding and cleaning process of stainless steel welds using a continuous laser. We varied cleaning parameters such as the distance from the laser beam focal point, power, and scanning speed. The results were visually assessed and organized into a matrix. We have determined that surface is not only cleaned, but also partially melted.

Keywords:laser cleaning, stainless steel, laser welding, continuous laser, oxide layers, heat tint
