AB  - This paper is based on extensive research about the influence of multiple different welded joint defects on the integrity of welded structures. In this particular case, the focus was on the heat affected zone and its different sub regions - up to this point, it was observed as a whole, with homogeneous mechanical properties along its cross-section. Due to the need to describe its behaviour in more detail, it was concluded that metallographic characterisation of the heat affected zone is necessary. Metallographic tests have provided a detailed insight into the micro-structures with the heat affected zone, which would be difficult to predict in this case, due to specific conditions, i.e., a welding technology which was adopted with the purpose of deliberately causing a number of defects in the welded joint. This would result in a more realistic distribution of mechanical properties along the heat affected zone, which in turn would provide more accurate input data for numerical simulations, since the use of finite element method will be the next step in this research.

AB  - The selection of the electrode for repair welding is one of the activities needed before repairing machine parts. In this case, damages that have occurred in a burner pipe welded joint during manufacture or previous repair welding have resulted in the need to replace the previously used electrodes with more suitable ones for the exploitation conditions to which the burner is subjected. For this purpose, 2 specimens welded with 2 different electrodes (Castolin and 6825 and PIVA 25/20 B) are cut from the pipes and tested. Micro- and macro-analyses of these specimens are performed, along with hardness testing. It is concluded that the Castolin 6825 electrode is better suited for burner pipe repair welding. Following this, the test repair welding of the burner pipe is performed. In addition to penetrant tests of the welded pipe, a short overview of the techno-economic analysis of the repaired pipe is given, including the ratio of repair price to the price of manufacturing a new burner.
