The diploma thesis deals with the technology of welding aluminum alloy AW 5754 by a method of arc welding TIG and with covered electrode. Introduction contains information about aluminum alloys and their labeling according to ČSN EN 573-1,2. Additional attention is focused on evaluation of the weld quality according to ISO 10042 and subsequent evaluation of the defects according to ISO 65 20 to 1. In the experimental section was welded samples tested at first by non-destructive methods (visual, capillary, X-ray testing) and followed by a destructive measurement of the weld (evaluation of micro-hardness, macroscopic and microscopic tests, tearing issues). Furthermore, part of weldments was subjected to a laboratory corrosion test in an aggressive environment of a salt chamber and then evaluating of mechanical properties of welds in both methods.
