Influence of Repair Welding on Weld Quality of Al Alloy EN AW 6082-T6
Original language description
This article focuses on repeated repair GMAW welding of precipitation hardenable Al alloy EN AW 6082-T6. During GMAW welding it may occur that weld needs repair because of presence of unacceptable weld defects, such as cracks and porosity. These defectsneed to be removed and welded again to be repaired. Such repair welding procedure is believed to have detrimental influence on weld joint quality because of multiple heat cycle, especially if the repair welding is done repeatedly (twice, three times). Toobjectively estimate influence of repeated repair GMAW welding on weld quality, V joint butt welds of 10 mm thick sheet were done. After welding the samples were mechanically tested, weld has been removed by grinding and welded again. This process was repeated up to 4 times. After each repair weld, the weld quality was assessed by visual and penetration non destructive tests and by tests of mechanical properties. Tensile strength and bend test, microhardness were measured. Microstrucure
