This paper deals with the experimental investigation of fatigue strength of AA 5083 and AA 6009 aluminium alloy welded joints. Testpieces consisted of 3 mm thick plates with different welded joints: butt welds and lap fillet joints, both MIG welded. Fatigue tests under constant amplitude loading, as well as tension tests and reverse bend tests were conducted. Tests were repeated, taking account of both the as-welded bead and the levelling of the weld bead. A comparison was made of experimental data on strength characteristics as well as those of national and international design standards. © 1998 Taylor and Francis Group, LLC.

Abstract
This paper deals with the experimental investigation of fatigue strength of AA 5083 and AA 6009 aluminium alloy welded joints. Testpieces consisted of 3 mm thick plates with different welded joints: butt welds and lap fillet joints, both MIG welded. Fatigue tests under constant amplitude loading, as well as tension tests and reverse bend tests were conducted. Tests were repeated, taking account of both the as-welded bead and the levelling of the weld bead. A comparison was made of experimental data on strength characteristics as well as those of national and international design standards. © 1998 Taylor and Francis Group, LLC.File in questo prodotto:
