Aluminum alloys ever more widely adapt (besides aviation and space equipment) for preparing the welded constructions. The production of welded cisterns for the transport of gasoline and dry cement is one of the applications of aluminum alloys. In Russia the widest application for preparing of gasoline tank trucks and cement carriers obtained aluminum the alloy of AlMg5 to be welded. For preparing the cistern are used the sheets of the alloy of AlMg5 with a thickness of 6–7 mm, whose welding in the construction is accomplished with the application of plasma welding by the nonfusible electrode and semiautomatic welding by the melting electrode in the inert gas (argon). The promising material for preparing the tank trucks, which possesses higher mechanical properties in comparison with the alloy of AlMg5, is the alloy of 1565, supplied by the company of Alсoa Russia. Are studied the special features of structure and property of butt joints of the annealed sheets from the aluminum alloy of 1565, obtained by argon-arc and plasma welding. Is investigated the influence of the composition of welding wire on the properties and the structure of the welded joints of the annealed sheets from the alloy of 1565. Are investigated the properties of the welded joints of the alloy of 1565M with the alloys of AlMg5M and AlMg6M. It is established that the strength of connection in this case is determined by the properties of less durable alloy (AlMg5M and AlMg6M).
