Abstract
Lasersko varjenje omogoča hitro, natančno in fleksibilno spajanje materialov, zato se vedno bolj uporablja v številnih proizvodnih področjih. Diplomska naloga je povezana z nadzorom laserskega varjenja, ki temelji na uporabi videokamere za spremljanje širšega območja varjenja. Opisan je razvoj osvetljevalnega LED modula, ki se uporablja za osvetljitev opazovane površine tako, da se poleg bazena taline z videokamero vidi tudi širša okolica, kot je stik med pločevinama. Na podlagi izhodiščnega sistema smo izbrali glavne parametre, ki jih je potrebno upoštevati pri snovanju osvetlitve za nadzor varjenja. Razvili in izdelali smo vodno hlajeno konstrukcijo za LED diodo, pri kateri temperatura delovanja ne presega 35 °C ob svetlobni moči 6,4 W. Predstavili smo različne intenzitetne profile, ki jih lahko dobimo z nastavljanjem oddaljenosti fresnelove leče od LED diode. Na koncu smo predstavili uporabo razvite osvetlitve pri spremljanju laserskega varjenja.

Title:Development of lightning system for video surveillance of laser remote welding
Abstract:
Laser welding enables fast, accurate and flexible joining of materials, so it is increasingly used in many production areas. Thesis is related to laser welding control, which is based on the use of a video camera to monitor a wider area of welding. The development of the LED lighting module is represented, which is used to illuminate the observed surface so that, in addition to the melt pool, a wider environment, such as the contact between the sheets, can be seen with a video camera. Based on the initial system, we select the main parameters that need to be considered when designing illumination for welding control. We develop and manufacture a water-cooled structural for LED diode of which the operating temperature does not exceed 35 °C at a light power of 6.4 W. We present various intensity profiles that can be obtained by adjusting the distance between the fresnel lens and the LED diode. In the end, we present the use of the developed illumination in the monitoring of laser welding.

Keywords:design and development, LED lighting diode, laser beam welding, water cooling, laser welding control system
