THE INFLUENCE OF ADDITIONAL MATERIAL ON THE ALLOY'S "EN AC 46400" WELDABILITY IN THE AUTOMOBILE'S OIL TANK

U ovome radu opisan je utjecaj dodatnog materijala na zavarljivost legure „EN AC 46400“ automobilskog spremnika ulja. U uvodu se govori općenito o TIG postupku zavarivanja i ukratko se opisuje Al-Si legura kao i njezine prednosti i nedostatci. Navode se postupci zavarivanja aluminijskih legura i sama zavarljivost aluminijskih legura kao i problemi prilikom zavarivanja. U nastavku se opisuje i razrađuje priprema epruveta i navode se vrste legura kojima se zavaruju, kao i prednosti i nedostatci zavarenih spojeva AlSi5 i AlSi12 legurom. Radi se simulacija na statičku vlačnu probu dobivene Al legure te legura dodatnih materijala u Autodesk Inventor. Na kraju je prikazan proces ispitivanja dobivene vrijednosti. Zaključak je baziran na proces ispitivanja i zavarljivost AlSi9Cu1 legure u ovisnosti od dodatnog materijala (AlSi5 i AlSi12).The influence of additional material on the alloy's („EN AC 46400“) weldability in the automobile's oil tank The introduction generally reffers to the TIG welding process and briefly describes the Al-Si alloy as well as its adventages and disadventages. Aluminium alloy welding procedures and aluminium alloy weldibility itself as well as problems occurring throghout welding. The following describes and elaborates the preparation of the test tubes, specifying the types of alloys to be welded with and listing the pros and cons of welded joints with both AlSi5 and AlSi12 alloy. Next a static tensile analysis of the obtained Al alloy and alloys from additional materials is made with Autodesk Inventor softwere. At the very end,the process of testinog of the obtained value is presented. The conclusion is based on the test process and weldability of the AlSi9Cu1 alloy depending on the additional (AlSi5 and AlSi12)
