Technical characteristics

The demand for aluminum products in industry and households is due to the positive performance qualities of this metal. However, its welding is associated with a number of difficulties. The method of pulse electric welding (MIG/MAG) using a welding semiautomatic machine has the lowest labor intensity. This method eliminates the effect of a thin surface film of metal oxide and results in a reliable connection.

Welding wire and shielding gas

When welding aluminum alloys using MIG/MAG method, it is necessary to use welding wire, which has a surface shielding. In this case, welding itself, to prevent oxidation of metal is carried out in shielding gas. The density of such gas increases, so argon, but not nitrogen or carbon monoxide, is used in practice. Supplying the filler wire is carried out automatically from a special unit, and the welder moves the torch manually.

Relevance of argon

A protective atmosphere is necessary, otherwise the weld is porous and much less strong, and the slag formed during welding is difficult to separate from the metal, Also, without a protective atmosphere there is an intensive spattering of aluminum. Supplier Evek GmbH offers to buy aluminum of domestic and foreign production at an affordable price in a wide range. We provide product delivery anywhere in the continent. The price is optimal.

Relevance of welding wire

Welding by MIG/MAG method is especially used in such industries as aircraft and shipbuilding. The wire, which is used for this method of welding aluminum, has the following composition (aluminum base):

Chemical element Silicon Iron Copper Manganese Magnesium Chrome Zinc Titanium
Content, % 0,08 0,11 0,02 0,12 4,95 0,13 0,006 0,13

Mechanical characteristics of the wire should meet the following requirements:

  • Tensile strength, MPa - 260...270;
  • yield strength, MPa - 120...125;
  • Elongation, % - 27 ... 25.
