Forestry is characterized by a diversity of natural conditions, which need to be adapted not only to the selection and application of technological processes, but also to the materials used in the construction of individual parts of the equipment. The article deals with the possibility of replacing steel elements with aluminium ones for selected parts of the adapter frame designed for liquidation of forest fires. The aim is to achieve a gradual reduction in its total weight. The aluminium sheet AlSiMgMn EN AW-6082 was selected a replacement for the steel parts. The filler material was solid wire AlMg5Cr. Welding was performed by the MIG method. The selected welding parameters should guarantee the creation of a quality joint that can replace steel weld joints, while respecting the demands placed on them. Weld joints were analysed by macroscopic analysis, measurement of hardness by HV1 and SEM analysis of welded joint with EDX analysis. The results of the laboratory experiment show that by the chosen welding procedure with given parameters, quality welded joints were achieved. After further analyses, these weld joints can be recommended as a substitute for the previously used weld joints of steel structures.

Keywords: welded joint, AlSiMgMn, hardness, microstructure, adapter of forest technic
