Abstract
U ovom radu opisana je problematika korijenske zaštite pri TIG (eng. Tungsten Inert Gas) zavarivanju austenitnih čelika. U teorijskom dijelu dat je pregled svojstava austenitnih čelika, kratki pregled TIG postupka i metode mjerenja kisika pri zavarivanju, utjecaj različitih zaštitnih plinova s naglaskom na njihov utjecaj na kvalitetu korijena zavara i naposlijetku korozijski mehanizmi koji se mogu javiti u području zavarenog spoja. U eksperimentalnom dijelu provedeno je navarivanje austenitnih Cr-Ni čeličnih cijevi s različitim zaštitnim plinovima (Argon 4.8, Argon 5.0, Inoxline H5) i udjelom kisika u atmosferi korijena zavara. Uzorci su kasnije dani na testiranje na koroziju čime se utvrđuje korozijska postojanost i na temelju kojih je moguće dati općenite preporuke za primjenu u proizvodnim uvjetima.
Abstract (english)
The problems with TIG welding of austenitic steels are described in this paper. An overview of the properties of austenitic steels, TIG welding process, oxygen level monitoring during welding, the influence of different shielding gases on the weld root and corrosion mechanisms that occur in the weld area are given in the theoretical part. Welding of austenite Cr-Ni stainless pipes is conducted in the experimental part with different gases (Argon 4.8, Argon 5.0 and Inoxline H5) and with different oxygen levels in the atmosphere near the weld root. Corrosion testing is then conducted on the samples and corrosion resistance is determined based on which general recommendations for real-life applications.
