Features of TIG welding technology

Aluminum products are covered with a surface film of refractory alumina. Since its melting point is much higher than that of the base metal (2000 ° C vs. 660 ° C), during normal welding it would be necessary several times to increase the current to melt it. The solution to the problem consists in the simultaneous application of two factors:

  • Use of an electrode made of refractory metal (most often, tungsten);
  • The use of inert gas — argon — which would effectively protect the arc burning zone from accessing there oxygen of air, which will actively oxidize the metal in the zone of formation of the welded seam.

The TIG method is used in both variants — with alternating or direct current. The reverse polarity is used. During the welding cycle, aluminum melts in the weld pool, without the formation of oxides. Supplier Avlob offers to buy aluminum at a bargain price. The price is the best in this segment of rental.

Additional conditions

TIG technology using alternating current is produced using tungsten electrodes, but this is not enough for a direct current. The following factors are also necessary:

  • The intermittent (impulse) method of feeding the filler wire, which takes into account the intensity of formation of the bath with the melt;
  • The use of aluminum alloy wire, however containing surface coatings made of high melting alkali metal salts;
  • The regulation of the power-law characteristics of the arc discharge — the current and voltage on the arc, which, in turn, determines the length of the arc.

For TIG welding, the use of direct current is optimal provided that the positive electrode is a tungsten electrode. In this case, you should use welding machines that support the function of automatic stabilization of the arc. To reduce wear of non-consumable electrode, it is recommended to use inverter welding equipment.
