Abstract: The present invention relates to a filler wire alloy composition including, in wt. %: Mg 6.0 to 9.5%, Mn 0.9 to 2.0%, Zn 0.2 to 0.9%, Zr?0.3%, preferably 0.05 to 0.25%, Cr?0.5%, Sc?2.8%, Cu?0.5%, preferably ?0.25%, Fe?0.5%, Si?0.5%, Ti?0.3%, the balance aluminium and incidental elements and impurities. The invention further relates to a welded structure welded together with the present filler alloy.

Abstract: An oil pan for a combustion engine includes two extrusions which are welded to one another so as to form an elongated chamber. The ends of the chamber are closed by covers. At least two partitions are disposed one above the other inside the chamber. The partitions extend transversely of the chamber and are carried by holders provided on the internal surfaces of the extrusions. Each of the partitions has an oil deflecting portion as well as two flat projections which protrude to opposite sides of the respective oil deflecting portion and serve to connect the partitions to the holders. The projections of each partition define a horizontal support plane for the respective partition while the oil deflecting portions define vertical surfaces for damping oil surges.
