Quality activities in the manufacture of welded structures and products

U završnom radu je kratko opisana povijest zavarivanja, sam postupak zavarivanja i aktivnosti na kvaliteti kod izrade zavarenih kotlovskih konstrukcija i proizvoda i koraci proizvodnje jednog proizvoda, komore pregrijača SH2. Na komori nakon zavarivanja se provode sljedeće operacije; toplinska obrada, vizualna kontrola zavarenog spoja korijena i lica zavara, dimnzionalna kontrola, zatim magnetska kontrola, kontrola hrapavosti i na kraju antikorozivna zaštita. Nakon što se završi izrada komore ona se povezuje zavarivanjem na ogrjevne površine pregrijača.In the graduate work, there is a brief description of the welding history, the welding procedure itself and the quality activities in the manufacture of welded boiler constructions and products and the steps of the production of a single product, the preheater chamber SH2. The following operations are performed on welding chamber; heat treatment, visual control of welded joints, dimensional control, magnetic control, roughness control and ultimately anticorrosive protection. Once the chamber is completed, it is connected by welding to the overheating surfaces of the overhead
