Aluminum alloys are among the materials characterized by poor weldability. Any experienced welder will confirm that to work successfully with aluminum, you need to have a lot of experience and know all the features of this metal. Technologically this process is quite complicated and a lack of experience can lead to manufacturing defects. Due to its high thermal conductivity, low melting point and the presence of a refractory oxide film, welding aluminum requires special equipment. TIG welding with shielding gas using aluminum alloy hard facing rods provides excellent joint quality.

Powder coating of metal is a popular technology that allows you to reliably protect the metal from corrosion while giving the product an attractive appearance. Each powder coating starts with pre-treatment. The surface of the metal is cleaned of rust, dirt and grease by chemical or mechanical means. Next, the product is placed in the paint chamber, where charged paint particles are sprayed over the surface with a paint gun. The products covered with a thin layer of powder are transferred to the furnace. Heating causes the paint to polymerize. As a result, a strong polymer film of the desired shade is formed on the surface.
