Abstract

Lasersko varjenje polimerov v zadnjem času močno prodira v industrijo, čeprav nam nekateri vplivi na uspešno varjenje še niso dovolj dobro znani ali pa so celo neznani. Diplomska naloga zajema raziskavo dejavnikov, dodatkov in lastnosti, ki vplivajo na prepuščanje in absorpcijo laserske svetlobe. Izkazalo se je, da je vplivnih veličin več in da je za nekatere, ki so zelo pomembne, težko vedeti, kakšen rezultat naj pričakujemo med varjenjem in kakšen bo videz zvara. S tem namenom sem v zaključnem delu pregledal znanstveno literaturo in pripravil primere za testiranja, s katerimi lahko odkrijemo ali dokažemo, kakšni so učinki vplivov. Ugotovil sem, da so najpomembnejši dejavniki temperatura varjenja, čas stiskanja oziroma držanja med varjenjem in vrsta materiala. Najtežja kombinacija varjenja je bela, najlažja pa črna, ker dobro absorbira lasersko svetlobo.

Secondary title:	Influence of parameters on laser welding of polymers
Secondary abstract:	Laser welding of polymers has been making strong inroads in the industry, even though some of the influences for successful welding are not yet well known. The bachelor thesis covers the research of factors, additives, and properties that affect the transmission and absorption of laser light. It turned out that there are several influential quantities, which are very important, it is difficult to know what result to expect during welding and what will be the weld appearance. To this end, the scientific literature is reviewed and test cases are prepared to detect or demonstrate the effects of the impacts. It was found that the most important factors are the welding temperature, the time of compression or holding during welding, and the type of material. The hardest combination for laser welding is white polymers and the easiest is black polymers, because they have better absorption of laser light.
