The article presents the research results of hardness distribution of friction stir welded joint (FSW) of AW-5083 aluminium alloy. During the study used two types of tools: with cylindrical pin and with conical pin. FSW is a method of welding in the solid state, mechanical properties of joints welded by that method can be higher than that for arc welding techniques (MIG, TIG). The parameters of friction stir welding (FSW) used for joining 5083 alloy sheets were presented. Metallographic analysis of chosen joints showed the correct construction of structural bonded joints. The study was carried out using Vickers hardness HV1 in accordance with the requirements of the Polish Standard PN-EN 6507 using a hardness and microhardness-testing machine FM-800. The location of measurement points in the butt joint was determined in accordance with PN-EN 1043-1:2000. The indenter load was 9.8 N. In order to identify areas of particular characteristic of bonded joints macroscopic examination was performed using an optical microscope ZAISS AxioVert A1 MAT. The test specimens were polished and then etched with KELLER reagent. This enabled the precise identification of zones present in the joint, such as weld nugget, thermo-mechanically affected zone and native material. Hardness testing in across researched joints showed that the change of welding parameters in the range proposed in the research does not impact on the hardness distribution in the weld.
