Hronologija gubitka integriteta konstrukcija zbog grešaka izrade zavarenih konstrukcija

Abstract

U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje je zahtevalo nova znanja i drugačiji pristup u rešavanju problema. Opsežne analize svih otkaza razmatranih u radu i izvedeni zaključci ipak nisu dovoljni da se potpuno izbegnu proizvodne nesavršenosti i obezbedi integritet zavarenih konstrukcija u eksploataciji. Direktive, standardi i preporuke za izradu zavarenih konstrukcija značajno doprinose rešavanju problema, ali ga ne mogu potpuno eliminisati zbog složenosti i velikog broja uticajnih faktora.

At different time periods, loss in structural integrity occurs from initiation of manufacture defects in the welded joint. Failure mechanisms are different and present a new experience always requiring new knowledge and approach in solving the problem. Extended analyses of all failures considered here and derived conclusions are yet not sufficient in completely avoiding manufacture imperfections and assuring in-service integrity of welded structures. Directives, standards and recommendations for manufacturing welded structures significantly contribute in problem solving which they cannot completely eliminate due to the complexity and numerous influencing factors.
