Pipeline welding in industrial plants

U ovom završnom radu cilj je bio opisati cjevovode, te način njihovog spajanja putem zavarivanja. U prvom dijelu rada opisani su općenito cijevi i cjevovodi, standardne norme cjevovoda, elementi cjevovoda koji su potrebni za normalno funkcioniranje, projektiranje cjevovoda i općeniti načini spajanja cijevi. U drugom dijelu završnog rada opisane su detaljno REL, MIG/MAG i TIG metode zavarivanja. Kroz navedene metode obuhvaćeni su opisi parametra zavarivanja, priprema radnog mjesta, opreme, izvor struje, tehnika zavarivanja, kontrola i toplinska obrada.In this final thesis the goal was to describe pipelines and the way of their joining by welding. The first part of thesis generally describes pipes and pipelines, standard norms of pipelines, elements of pipes which are needed for normal functioning, design of pipelines and general way of connecting pipes. The second part of thesis detail describes SMAW, GMAW and GTAW methods of welding. With mentioned methods are also described parameters of welding, preparation of workplace, equipment, sources of power, welding techniques, control and the heat treatment
