Abstract
U početnom, teorijskom dijelu rada dan je kratak pregled čelika koji se koriste za rad na visokim temperaturama. Detaljnije je opisan martenzitni čelik P91 te je dan poseban naglasak na problematiku zavarljivosti i promjenu mikrostrukture u području zavarenog spoja. Obrađena je problematika zavarivanja raznorodnih spojeva čelika P91 te je na kraju dan prikaz prikladnih dodatnih materijala na bazi nikla za zavarivanje čelika P91 s visokolegiranim austenitnim čelicima. U eksperimentalnom dijelu rada provedeno je zavarivanje ploča čelika X5CrNi18-10 i cijevi od čelika P91 primjenom Inconel 625 dodatnog materijala. Određeni su parametri zavarivanja te su zavarena dva spoja. Nakon zavarivanja, izrezani su uzorci te je provedena analiza mikrostrukture kao i mjerenje tvrdoće. Analizom rezultata dobivenih ispitivanjem doneseni su zaključci o zavarljivosti čelika X5CrNi18-10 i čelika P91.
Abstract (english)
First, theoretical part of this thesis gives a short overview of steels for high temperature applications. Martensitic steel P91 is thoroughly described and a special focus on the weldability of this material is given. Also the change of the microstructure in the welded joint is given. The weldability of dissimilar steels was also described and at the end of this theoretical part, nickel-based filler metals for dissimilar metal welding between high alloyed austenitic and martensitic steel P91 are given. In the experimental part of this paper, welding of X5CrNi18-10 steel plates and pipes of P91 steel with application of Inconel 625 filler metal was carried out. Welding parameters were determined and two welded joints were made. After welding, the specimens were cut out and microstructure was analyzed and hardness measurement was also performed. Analyzing the results obtained by testing, the conclusions on weldability of steel X5CrNi18-10 and steel P91 were adopted.
