Welding of aluminum by argon

Welding of aluminum by argon

Is aluminum welding with argon? Supplier Avlob offers to buy aluminum at a bargain price. The supplier guarantees the timely delivery of products to any address in Europe or abroad. Regular customers receive a discount discount. The price is the best in this segment.

Oxide film

In the open air, aluminum reacts with oxygen, as a result of which a thin film of Al 2 O 3 dioxide forms on the surface. It is characteristic that the melting point of this oxide film is more than 2000 ° C), while aluminum itself melts at a much lower temperature — 650… 660 ° C). Thus, when using DC electric welding, Al 2 O 3 dioxide can be part of the weld metal, thus violating its structure and properties.

Technological difficulties of welding

It is impossible to visually determine the heating temperature of aluminum, since the metal does not change its color. It should also be taken into account the low volumetric shrinkage of aluminum, which is why it is necessary to increase the consumption of the welding wire. Otherwise, residual stresses are generated in the weld zone. Supplier Avlob offers to buy aluminum at a bargain price. The price is the best in this segment of rental.

Sequence of operations

  • A non-consumable tungsten electrode with a diameter of 1.5… 5.0 mm is selected;
  • Setting the current-voltage characteristics of the welding machine: welding should be done by a short arc, not exceeding 3… 4 mm in length;
  • A sheet of stainless steel is placed under the future weld seam, which increases the heat transfer from the working area.
  • The filler wire is fed perpendicular to the axis of the welded parts, while the welding electrode is held at an angle of 75… 800;
  • The filler wire is always located in front of the electrode;
  • It is inadmissible to move the filler wire and electrode across the weld;
