Abstract
Diplomski rad pod nazivom „Zavarivanje polietilenskih cijevi i osposobljavanje zavarivača“ u prvom poglavlju govori općenito o polimerima te polietilenu. Opisane su polietilenske cijevi, njihov način primjene, karakteristike te njihove prednosti u odnosu na čelične cjevovode u distribuciji plina i vode. Polietilenski cjevovodi spajaju se zavarivanjem. Općeniti postupci zavarivanja polimera opisani su u drugom poglavlju, uz detaljniji opis elektrofuzijskog zavarivanja te zavarivanja pomoću grijaće ploče. Ta dva postupka predstavljaju najvažnije postupke pri izradi polietilenskih plinovodnih i vodovodnih sustava. Objašnjen je princip rada i postupak provođenja zavarivanja tim tehnikama spajanja. U četvrtom poglavlju opisan je postupak školovanja zavarivača i nadzor zavarivanja. Svaki zavarivač mora biti osposobljen za postupak kojim se cijevi spajaju. Također, objašnjen je i postupak kojim se ispituju uzorci zavarenih spojeva prilikom ispitivanja zavarivača i način provedbe nadzora zavarivanja. Prilikom zavarivanja, neovisno o osposobljenosti zavarivača, moguća je pojava grešaka u zavarenom spoju. Osposobljavanje zavarivača osmišljeno je i služi kako bi se pojave pogrešaka svele na minimum. Greške koje mogu nastati prilikom zavarivanja PEHD cijevi prikazane su i objašnjene u zadnjem poglavlju ovog diplomskog rada.
Abstract (english)
Graduation thesis „Welding of PEHD pipes and welder training“ in the first chapter speaks in general about polymers and polyethylene. Polyethylene pipes, their method of application, characteristics and their advantages in relation to steel pipeline sin gas and water distribution are described. Polyethylene pipelines are joined by welding. General procedures for welding of polymers are described in the third chapter, with a more detailed description of electrofusion and butt welding. These two processes represent the two most important processes in the construction of polyethylene gas and water supply systems. The principle of operation and the procedure of welding by these joining techniques are explained. The fourth chapter describes the process of welder training and welding supervision. When welding, regardless of the qualification of the welder, defects in the welded joint may occur. The welder training is designed and serves to minimize the occurrence of defects. Defects that can occur when welding PEHD pipes are represented and explained in the last chapter of this thesis.
