Laser welding

Uvodni dio teoretskog dijela temelji se na postupku nastajanja laserske svjetlosti. Nakon toga dat je opis pojedinih lasera koji se koriste za zavarivanje te njihove karakteristike. Obrađeni su parametri laserskog zavarivanja te njihov utjecaj na kvalitetu zavara. Konačno na kraju navedena je prednost spajanja u sustav laser-robot i primjene laserskog zavarivanja. Nakon teoretskog dijela rada uslijedio je eksperimentalni dio koji se bazirao na određivanju geometrije i strukture laserski izvedenih zavara izvedenih različitim brzinama zavarivanja.The introductory part of the theoretical section is based on the process of generating the laser light. After that the description of the individual lasers which are used for welding and their characteristics are given. Especially, the process parameters of laser welding and their influence on the quality of the weld were discussed. Further more, the advantage of integration in robot-laser welding system and the process industry applications are presented. After the theoretical part of this thesis the experimental part was conducted, based on the determining of the geometry and structure of the laser welds which are produced with different welding speed
