Abstract

Določanje globine prevaritve pri laserskem prekrivnem varjenju je pomembno za doseganje čim kvalitetnejših varov. Ker pa to ni trivialno, smo iskali metodo, s katero je bilo možno določiti prevaritev obeh materialov prekrivnega spoja. Z vlakenskim laserskim virom smo varili pločevine aluminija, bakra in jekla AISI 304, najprej posamično, potem pa še v prekrivnem stiku. Emisijo svetlobe plazme, ki je nastajala, smo zajemali s spektrometrom. Ugotovili smo, da ima vsak material značilen spektralni odziv in da je možno, ko sta spodnji material aluminij in jeklo, zaznati njuno prevaritev z metodo opazovanja spektra.

Secondary title: Spectral observation of laser welding of various materials
Secondary abstract: Determining the depth in laser overlay welding is important for achieving the highest weld quality. But since it is not trivial, we searched for a method, that would allow us to determine penetration of both materials in an overlap joint. Aluminum, copper and AISI 304 steel were welded with a fiber laser source, first individually and then in overlapping contact. The resulting plasma light emission was recorded with a spectrometer. We have found, that each material has a typical spectral response and that when the underlying material is aluminum or steel, it is possible to detect their penetration by means of spectral observation.
