“…Evaluations that were extended to dissimilar welding by performing quality assessments of dissimilar welded joints of Hardox 450 and Strenx 700 involving non-destructive testing and microstructural analysis unveiled the significance of welding consumables in achieving the required quality of welded joints [14]. Moreover, the weldability of ultrahigh-strength steel and advanced high-strength steel was examined [15] by investigating the welds of S700MC/S960QC, which further demonstrated the importance of precise welding processes and parameters.…”

The paper evaluates the possibility of using dissimilar materials joined by welding technology in the construction of agricultural machinery. The desire to design larger and more efficient structures requires designers to combine materials with different mechanical and structural properties. In such a case, it is very important to properly select welding parameters so that, on the one hand, the quality of the joint meets the standard requirements, and on the other, the welding process is not too energy-intensive. In this paper, overlay joints connecting S355 steel with Strenx 700 steel were analyzed in terms of strength for three different values of welding parameters and different thicknesses. The starting point was the reference parameters recommended by the company’s welding technologists, which were reduced by 10 and 20% according to the linear welding energy. The study compared the strength, ductility and macrostructure of the joints, as well as the energy intensity of the process. The proposed dissimilar joints achieved approximately a 10% increase in the strength limit of the components in comparison to the previously recommended welding parameters. Additionally, finite element analysis calculations of the improved designs showed significant weight reduction (up to 40%) for the relevant agricultural machinery components.
