AB  - This paper deals with damage analysis of gear ring after manufacturing process, just before in-service period. Tooth gear ring segments were made of 40MnCrSi3V low-alloyed cast steel, which chemical composition and mechanical properties were given in table 1 and 2, respectively. Concerning parent material characteristics, in this case low-alloyed cast steel 40 MnCrSi3V, inspection and control of gear segments were necessary to be performed after manufacturing. Non-destructive testing method with magnet particles (MT) of fluorescent suspension of particle size 3 µm was performed for potential defects detection. Surface indications were observed on 8 out of 12 gear segments on these new parts, where the lengths of the cracks goes up to 110 mm. Some of the observed defects were shown in Fig. 1. Defects were located in segments main body the gear teeth, its main body etc. Taking into account aforementioned, observed defects on new gear ring segments were caused in manufacturing process i.e. by casting process and inadequate cooling rate.

AB  - The research covers the investigation of mechanical properties of welded joint made on NiCr21Mo alloy (commercial trademark Incoloy 825), and joints of steels P355GH and X2CrNiMo17-12-2, as well as the influence of the achieved mechanical properties on structural integrity. Ongoing research is oriented on welded joints made of NiCr21Mo, i.e., the alloy to be introduced for certain parts (made of the aforementioned materials P355GH and X2CrNiMo17-12-2) of processing equipment exposed to elevated temperatures and high corrosive environment. Three preliminary welding technologies are presented in the first part of the paper. Tungsten inert gas (TIG) welding technique is used due to the type of filler material. The filler material features mechanical properties that provide an overmatching effect. After non-destructive tests (NDT), mechanical properties of all three welded joints are examined according to criteria that guarantee safe work and welded component integrity. In addition to mechanical tests (uniaxial tension, bending, impact toughness, hardness measurements), a microstructural analysis is performed to verify the applied preliminary welding technologies and evaluate the integrity of the obtained joints. After analysing all tests it is confirmed that the application of the preliminary welding technology has met all the requirements according to the applied criteria.
