Abstract:Namen diplomske naloge je prikazati načine ščitenja korena zvara pri varjenju cevovodov iz avstetnitnih nerjavnih jekel. V delu so opisani postopki varjenja ter materiali, ki se uporabljajo v farmaciji in kemijski industriji. Opisani so postopki, s katerimi ščitimo koren zvara, ter posledice, ki nastanejo pri nepravilni zaščiti, prav tako pa so navedeni tudi razlogi, zakaj je koren sploh potrebno ščititi. Na koncu so prikazani rezultati eksperimentalnega dela, kjer je razvidno, kako različne zaščite korena zvara vplivajo na kvaliteto zvarjenega spoja. Ocenjevanje kvalitete zaščite korena zvarnega spoja je izvedeno na podlagi stopnje obarvanosti po AWS D18.1.

Title:ROOT WELD METAL SHIELDING AT WELDING OF AUSTENITIC PIPELINES WITH DIFFERENT QUALITIES IN PHARMACY AND CHEMICAL INDUSTRY
Abstract:The main purpose of the diploma thesis is to show methods of protecting weld root in the welding of austenitic piping. Protection of weld root is essential because of its huge impact on quality and corrosion resistance of weld joints. Procedures of welding and materials which are used in pharmacy and chemical industry are presented in this paper. There are described procedures of protecting weld root and consequences due to improper protection. Reasons for root protection and results of experimental work are emphasized. Therefore different weld root protections were examined and their impact on the quality of welded joint was specified. Quality evaluation of protection of welded joint was performed using weld discoloration chart due to AWS D18.1
Keywords:welding, protection of weld root, corrosion, austenitic steel
