mm izrađene od čelika povišene čvrstoće, oznake X65. Ključne riječi: – cijevi – automatizirano zavarivanje – off–shore industrija – ispitivanje kvalitete zavarenih spojeva Abstract: Welding automation is a necessity, especially in the offshore and oil industry where the welding should be effective and high quality of the welded joint should be achieved. The paper describes an example of automated pipes welding with an outside diameter and 48' ' (1.21 m), wall thickness of 30.9 mm, made of higher strength steel X65
