Abstract The article presents the impact of welding imperfections on the strength and microhardness of AW 5754 aluminium alloy welded joints executed with the TIG method. It presents the results of tomographic tests of welds. The results of strength and microhardness tests involving welds executed under various welding process parameters were shown. The impact of welding imperfections on the strength and microhardness of a welded joint was analysed. Based on analysing the relations between the r Pearson coefficient values and multiple correlation, significant relationships between strength, hardness and weld defects were evidenced. Furthermore, a very strong relation between the welding process parameters, welding imperfections, and weld strength and microhardness was shown.
