Abstract
U ovom diplomskom radu je obrađena problematika podvodnog zavarivanja cjevovoda čelika X70 prema API 5L. Općenito je objašnjeno podvodno zavarivanje, odnosno podjela podvodnog zavarivanja na suho i mokro. Obrađen je REL postupak mokrog podvodnog zavarivanja, objašnjene su fizikalne osnove procesa, tehnike rada, a također je opisana oprema za zavarivanje kao i oprema ronioca-zavarivača. Jedno poglavlje posebno je posvećeno razvoju čelika povišene čvrstoće, te njihovoj zavarljivosti i primjeni u praksi. Problemi koji se javljaju kod podvodnog zavarivanja opisani su u posljednjem poglavlju, a poseban naglasak je na hladne pukotine, te su također opisane neke metode ispitivanja sklonosti hladnim pukotinama.
Abstract (english)
This graduate thesis deals with issues of underwater welding of steel pipeline X70 according to API 5L. There is general explanation of the whole underwater welding process also as two welding types, dry and wet one. We processed MMAW procedure of wet underwater welding, explained the physical basics of the process and described equipment needed for welding process, also as for weld divers. One chapter is about high-firm steel and its weldability. Problems that occur during the welding are well explained in the last chapter with the accent on cold cracks and its preference test methods.
