Comparison of welding influence on structural strength of Al-Mg-Si alloy (AW6082-T6), supplied with 10 mm thick sheets, is made. Within the research tension and impact tests of welding joints, made with argon-arc and friction stir welding, were carried out. During the research we observed the following: strength and plasticity decrease for welding joint zones, impact strength increase of weld metal in friction stir welding, welding defects influence on joint strength.
