The demand for aluminum products in industry and everyday life is associated with the positive performance of this metal. However, its welding involves a number of difficulties. The minimum time consuming is the method of pulsed electric welding (MIG / MAG) with the use of a welding semiautomatic device. This method allows to exclude the influence of a thin surface film of the metal oxide, and as a result to obtain a reliable connection.
Welding wire and shielding gas
When welding aluminum alloys by the MIG / MAG method, it is necessary to use a welding wire that has surface protective coatings. In this case, welding itself, in order to prevent the oxidation of the metal, is conducted in a protective gas environment. With an increase in the density of such a gas, the reliability of protection increases, so in practice, argon is used, and not nitrogen or carbon monoxide. The filler wire is fed automatically from a special unit, and the welder moves the burner manually.
Urgency of argon
A protective atmosphere is necessary, otherwise the welding seam is obtained porous and much less durable, and the slags formed during welding are difficult to separate from the metal; Also, without a protective atmosphere, there is intense spattering of aluminum. Supplier Evek GmbH offers to buy aluminum of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Relevance of the welding wire
Welding using the MIG / MAG method is especially used in such industries as aircraft and shipbuilding. The wire used for this method of aluminum welding has the following composition (base-aluminum):
The mechanical characteristics of the wire must meet the following requirements:
- The limit of temporary resistance, MPa — 260… 270;
- Yield strength, MPa — 120… 125;
- Relative elongation,% — 27… 25.
