Description

Rod for welding of pure and near pure aluminum
Pure aluminum commonly used in the food industry, in electrical engineering, in the chemical sector, and in metallization. It is characterized by good fluidity and increased corrosion resistance. This rod has been improved with Ti to refine the grain and is weldable in all positions. Suitable for pure aluminum and nearly pure aluminum (max 0.5% alloying elements). Consumables suitable for welding pure aluminum and pure aluminum alloys.

Description

Application

Aluminum consumables designed for the welding of primarily pure aluminum-based alloys, containing a maximum of 0.5% alloying elements. The addition of titanium acts as a grain refiner, providing the material with unique properties such as enhanced corrosion resistance. These characteristics make the alloy ideal for applications in the chemical, construction, and food industries, as well as in electrical engineering and metallization. The alloy is also used in spray, arc, and flame metallization.

Alloy Type

Consumables suitable for welding aluminum and pure aluminum alloys.

Microstructure

Pure aluminum (i.e. with a minimum aluminum content of 99.50%) presents a face-centered cubic (fcc) microstructure.

Welding & PWHT

The surface of a weld typically presents oxides and welding stains. This dirt, gray-black in color, consists of aluminum oxide and magnesium oxide. Before proceeding with further weld passes, it is advisable to remove these stains and oxides, as they can cause fusion defects. Removal is most effective using a wire brush, either manual or electric, that should be clean and dedicated exclusively for use on aluminum. The high melting and solidification rate of the weld metal, typical of the gas metal arc welding (GMAW) process, can lead to the entrapment of gaseous hydrogen in the welds. It is essential to carefully control this aspect to ensure optimal results. For thicker plate materials, preheating to 150 °C is necessary to ensure better performance in welding.
