Aluminum alloy welding in automotive industry

The paper presents the possibilities of using light alloy components in vehicle construction. Material 6082 was chosen for use in responsible structural components. The structure and strength parameters of the material in the delivery state were tested. Tested material parameters were compared with normative requirements. The purpose of the paper is to check the mechanical properties of aluminum alloy welded joints by various processes and parameters. Until now, welding of 6082 alloy did not give good and repeatable results. Because of that, two welding methods were analyzed (MIG and TIG) in the field of the quality of welds, strength of welded joints, and material structures obtained as a result of welding with various parameters.
