摘要：In this study, GeKa Tempo B65 electrodes are used in the welding of high strength low alloy (HSLA) S355JR steel. It is aimed to increase the impact resistance of the electrodes at minus temperatures. In order to observe the mechanical properties of the materials, tensile, impact energy test and CTOD test are performed. Implicit electric arc welding is chosen as the welding method. Electrodes with three different compositions and grain structures are prepared for welding. Optical microscope is used to observe the surface images of the weld seams. It is observed that the grain structure of the sample, the amount of alloying elements and the heat input during the welding of the sample significantly affect the impact resistance of the welded samples.
