Aluminum welding: Types and applied techniques

Aluminum welding consists of joining two metal components by melting them together, the material used being aluminum. This material requires experience and precision. Welding aluminum is not as easy as it sounds. You need the right equipment and tools, as well as soldering with patience and finesse.

However, aluminum also offers great advantages as it is a lightweight material (much more than steel) with high electrical conductivity and better corrosion properties than steel. For this reason, aluminum is increasingly used in industrial applications.

To ensure quality in aluminum welding, it is necessary to take into account:

Selection of welding equipment
Base Metal Preparation
Application of the proper technique
Visual inspection of welds
Even for experienced steel welding professionals, aluminum alloys can be challenging. Cleaning before welding is also important. It is a fundamental matter to achieve good results. Dirt, debris, oils, moisture and oxides must be removed. This cleaning can be done through mechanical or chemical means.

Types of aluminum welding: techniques and machinery
There are several types of aluminum welding. At Favram S.L. We have the Certification of the EN 15085 standard. We have complete welding stations with groups for welding with TIG - MIG - MAG, pulsed arc, plasma and insert welding, welding robots capable of welding large series in reduced times.

The shielding gases used are the inert gases Argon and Helium. During welding, the inert gas cools the welding nozzle and protects the electrode and the melt pool at the same time. The gas also participates in the electrical process in the arc. There are three main techniques:

Arc welding under an inert atmosphere with refractory electrode or TIG (Tungténe Inert Gas) procedure.
Arc welding under inert atmosphere with consumable electrode or MIG (Metal Inert Gas) procedure.
MAG welding: metal active gas welding (Metal Active Gas).
MAG welding differs from MIG welding because of the gas that is injected. Also known as GMAW (Gas Metal Arc Welding or "gas metal arc welding") it is a process of arc welding under shielding gas with a consumable electrode. Argon, carbon dioxide or oxygen mixtures are used as shielding gases. Due to its high productivity and profitability, it is one of the most widespread joining procedures. Another advantage is the high process safety and reliability.
