Flux cored arc welding

U teoretskom dijelu rada je prikazana podjela zavarivanja i značajke elektrolučnog zavarivanja u zaštitnoj plinskoj atmosferi sa svojim prednostima i nedostacima, potreban alat i oprema, te važnost parametara u zavarivanju. Kao jedan dio elektrolučnog zavarivanja, obrađena je upotreba praškom punjene žice u zaštitnoj plinskoj atmosferi i tehnološki postupak zavarivanja tom žicom. Odabran je “V” spoj za zavarivanje u vertikalnom položaju zavarivanja prema gore, te opis njegove pripreme za zavarivanje. Odabrani su parametri zavarivanja za taj spoj prema certifikatu No 667/RJK/13 zajedno sa potrebnim alatom i ostalim karakteristikama.The theoretical part of the thesis presents the division of welding and the abilities of arc welding in a protective gas atmosphere with its advantages and disadvantages, the necessary tools and equipment, and the importance od parameters in welding. As part of the arc welding, the use od powder-filled wirw in a shielding gas atmosphere and the technological process of welding is described. The ''V'' welding joint in the vertical upward welding position is selected, and a description of its welding preparation. The chosen welding parameters for this joint are according to the certificate No 667/RJK/13 along with the necessary tools and characteristics
