Aluminum vessel welding procedure

U radu je opisan proces zavarivanja aluminijskog plovila ECO 13. Navedene su dobre mehaničke osobine aluminija i aluminijskih legura koje su zaslužne za njegovo sve šire korištenje u brodogradnji. One pridonose i poteškoćama pri zavarivanju aluminija naročito kako smo spomenuli i detaljno opisali pojavu Al2O3na površini materijala. Pri zavarivanju aluminija koristimo MIG, MIG-impulsno i TIG zavarivanje. U radu su opisani parametri, ostale karakteristike te način rada pojedinog postupka. Opisano je korištenje dodatnog materijala i zaštitnog plina koje je propisano standardima za svaki pojedini postupak. Naročito je bitno pažnju posvetiti čistoći i načinu skladištenja žica, šipki i plina te skladištenju, manipulaciji svih limova, traka i profila. Određeni su redoslijed i smjer te potrebni parametri zavarivanja pri izradi aluminijskog plovila. Provjera kakvoće proizvoda odnosi se na kontrolu poluproizvoda i proizvoda koji se moraju kontrolirati prije, tijekom i nakon zavarivanja.The thesis paper describes the process of welding aluminum vessel ECO 13. There are good mechanical properties of aluminum and aluminum alloys which are responsible for it is wider use in shipbuilding. They also contribute to aluminum welding difficulties, particularly as we mentioned and described in detail the appearance of Al2O3 on the surface of the material. In welding of aluminium we use MIG, MIG impulse and TIG welding. There are describes the parameters, other characteristics and the way of each process is performed. The use of additional material and protective gas are prescribed by the standards for each particular process is described. It is important to pay attention on the purity and storage of wires, rods and gas and also storage, manipulation of all sheets, strips and profiles. The order and direction and also the welding parameters required for the manufacture of aluminum vessels are determined. Product quality control refers to the control of semi-products and products that must be controlled before, during and after welding
