Aluminum wire: types and applications

The most common filler materialfor various types of welding is aluminum welding wire. This material is widely used in the technological processes of automatic and semi-automatic welding. The continuity of the process, the high quality of the seam obtained, the self-regulation of the feed rate in the welding area - these are far from all the advantages that aluminum wire possesses.

Aluminum wire

The well-known rule is that the materialwelded parts should be similar in composition to the used filler. This condition becomes especially important, since it depends on it the quality of the weld, its durability and strength.

Aluminum wire is often used forwelding of metals of similar composition. For example, for automatic and semi-automatic welding of materials such as alloyed, carbon or stainless steel, as well as, of course, aluminum-manganese alloys and aluminum parts. Gas welding is best suited for welding a filler wire on the seam.

Welding aluminum wire presentsby itself a wire tape. This is a kind of flexible electrode that will perfectly replace the more fragile and costly elements that can be used during manual processing.

Aluminum wire is made from sheetaluminum by stretching and then cutting into pieces of the required length. Firms-manufacturers are engaged in realization of many types of similar products.

Depending on the type of production, aluminumThe wire can have different characteristics, different requirements can be presented to it. Consequently, the manufacturer must produce the required products. Whether the aluminum wire is of different length and cross-section, the buyer's requests must be satisfied.

Aluminum is a universal material thatcharacterized by sufficient strength and reliability, ease of use and high degree of flexibility, has a relatively low cost and low weight.

The following types of aluminum wire are distinguished:

  1. Powder coating.
  2. Copperplated.
  3. Stainless.

Welding aluminum wire

Each of these types has its own characteristicsapplication. For example, the powder type is a small tube inside which there is an aluminum mixture in the form of a powder. This prevents oxidation and slag formation, and also helps stabilize the burning electric arc. Stainless wire is used to connect chromium-containing stainless steel and nickel. In turn, copper plated is used for welding parts made of alloyed cast iron and steel, which helps to prevent splashing of the metal and get welded seams of high quality.

To obtain a high-quality seam,only the selected material of filler surfacing, but also other factors, such as the temperature of the weld zone and the degree of surface treatment. This means that the melting point of the filler material should not be greater than the melting temperature of the parts to be welded, while the metal surface must be clean and dry, without any oxides, scales and paint traces.
