Abstract
U ovome radu napravljen je teorijski pregled postupaka elektrolučnog zavarivanja s detaljnim opisom postupka elektrolučnog zavarivanja netaljivom elektrodom pod zaštitom inertnog plina. Opisan je osnovni princip elektrolučnog zavarivanja te je istaknut utjecaj ključnih parametara na kvalitetu zavarenog spoja. Navedeni su uređaji i vrste elektroda koji se primjenjuju kod elektrolučnog zavarivanja s netaljivom elektrodom pod zaštitom inertnog plina. U eksperimentalnom dijelu rada provedena je metalografska analiza mikrostrukture sučeono zavarenog spoja cijevi i redukcije. Iz zavarenog spoja cijevi izrezani su ispitni uzorci iz četiri različite zone koje obuhvaćaju oba osnovna materijala cijevi, zonu taljenja i zonu utjecaja topline. Nakon rezanja ispitni uzorci su u uređaju za vruće izostatsko prešanje uloženi u praškastu vodljivu masu, nakon čega su brušeni, polirani i nagriženi nitalom kako bi se provela metalografska analiza. Provedenim metalografskim ispitivanjima zaključilo se da zona utjecaja topline ima sitnozrnatu strukturu, a zona taljenja lijevanu strukturu.
Abstract (english)
This paper provides a theoretical overview of welding procedures with a detailed description of the arc welding procedure with infusible electrode protected by inert gas. The basic principle of arc welding is described and the influence of key parameters on the quality of the welded joint is emphasized. The devices and types of electrodes that are used for electrostatic welding with an inert gas protection are listed. In the experimental part, a metallographic analysis of the microstructure of the welded pipe and reduction welds was performed. From the welded tube joint, test samples were cut out of four different zones, covering both of the basic materials, the melting zone and the heat transfer zone. After cutting, the test samples were placed in a hot isostatic press with a powdered conductive mass, after which they were crushed, polished and eroded with nital to perform metallographic analysis. The metallographic investigations carried out concluded that the zone of heat influence has a fine-grained structure and the melted zone has the cast structure.
