Abstract

Teorijski dio rada detaljnije opisuje postupak mokrog podvodnog REL zavarivanja. Objašnjene su osnovne karakteristike postupka te navedeni problemi koji se mogu javiti prilikom izvođenja istog. Opisana je oprema zavarivača ronioca kao i dodatni materijali koji se koriste pri izvođenju mokrog podvodnog zavarivanja, moguće opasnosti koje se javljaju te primjena samog zavarivanja.
Eksperimentalni je dio rada proveden na prostoru Fakulteta strojarstva i brodogradnje u Laboratoriju za zavarivanje. Mokrim podvodnim REL zavarivanjem zavaren je kutni spoj gdje je osnovni materijal izrađen od nehrđajućeg čelika. Nakon zavarivanja izrezan je jedan uzorak koji je nagrizen te mu je vizualnom kontrolom ocijenjena prihvatljivost zavarenog spoja prema normi AWS D3.6M:1999.

Abstract (english)

The theoretical part of the paper describes the procedure of wet underwater REL welding in more detail. The basic characteristics of the procedure are explained, as well as the problems that may arise during its performance. The equipment of the diver's welder is described, as well as the additional materials used in performing wet underwater welding, the possible dangers that occur and the application of the welding itself.
The experimental part of the work was carried out in the Welding Laboratory of the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb. Wet underwater REL welding welded the corner joint where the base material is made of stainless steel. After welding, one sample was cut and etched, and the acceptability of the welded joint was assessed by visual inspection according to the AWS D3.6M: 1999 standard.
