20.500.12556/RUL-149401 Spektralno opazovanje laserskega varjenja različnih materialov Spectral observation of laser welding of various materials 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. 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. lasersko varjenje spektrometer prekrivno varjenje spektralne linije laser welding spectrometer overlap joint spectral lines true false false [J.
