Welding difficulties

The use of conventional welding methods for aluminum products is not possible due to the following technological features of this metal:

• low melting point;
• a large coefficient of bulk metal shrinkage.
• rapid oxidation of hot aluminum, for the prevention of which argon is used.

Arc welding is carried out using filler wire. In arc welding, it performs the task of preventing internal stresses in the weld zone, since it compensates for undesirable volumetric shrinkage. Supplier Avlob offers to buy aluminum at a bargain price. The price is the best in this segment of rental.

Sequence of operations

Electric arc welding of aluminum products is performed on a direct current, with the reverse polarity of the process. Aluminum electrodes are used, or the filler wire, which has a coating of suitable fluxes. The most qualitative seam for permanent jointing of aluminum parts is provided by the apparatus for argon-arc welding. The electric arc is excited at the tungsten electrode. In the arc burning zone (a so-called «short» arc with a length of no more than 3… 4 mm is used), an aluminum filler wire is fed. The high temperature, which is created in the combustion zone, provides effective destruction of the surface film of aluminum dioxide, which is always present on the surfaces of the products to be connected. Significantly less often for welding use aggregates operating on alternating current.
