Abstract :In this study, the mechanical and metallurgical properties of the welding materials obtained from the combination of submerged arc welding powder and flux cored wire were discussed in detail for the first time in the sector. Chemical analysis of flux cored wire and submerged arc welding powder combination was carried out on the St-52 (S355) quality 300x180x20 mm sized low carbon steel materials. For mechanical tests, a gap of 16 mm was left between the materials and 10 mm thick S355 quality metal base was placed under the parts. Combining welding operations were 29 Volt voltage, 460 Ampere current, 450 mm/min welding speed, 1.75 kj/mm heat input and 30 mm free wire length. Microstructural properties were determined by metallographic methods and confirmed by mechanical properties. As a result of the evaluation of all the data obtained, the synergistic effect of the high efficiency of the flux cored wire method and the high energy input of the submerged arc welding method was observed, and the results were conveyed to the readers in detail.Keywords : Tozaltı Ark Kaynağı, Özlü Tel Kaynağı, Mekanik ve Metalurjik Özellikler
