The aluminum square tube refers to a square aluminum tube formed by extrusion of a direct current die by heating aluminum or aluminum alloy material. The application range of the aluminum square tube is very wide, and the aluminum square tube is simple to install and convenient to maintain. Since the aluminum alloy has a small density and can be processed into various shapes and specifications, the aluminum square tube heat sink has a large and regular cross section, and the product assembly and surface treatment can be installed in one step, and the construction site can be directly installed, saving A lot of installation costs. Maintenance is also convenient and inexpensive.

Welding method of aluminum square tube: It is recommended to use TIG or MIG method to weld aluminum alloy structure. Both ends of important welds should be equipped with fox plate and arc extinguishing plate. Tough welds for hull and superstructures can be TIG and MIG, and fillet welds for hull and frame are MIG. Welded aluminum alloy structure.
The welding groove method of aluminum alloy square tube is more special than ordinary materials. Generally, the opening type is selected according to the thickness of the plate, and double-sided welding is generally adopted. The processing of the welding groove should be processed by mechanical processing, and the burrs, flash edges and other factors affecting the welding quality should be removed, indicating that the roughness should not be greater than 12.5 um. Plasma arc cutting can also be used.
The commonly used alloys for aluminum square tubes are commonly used in AL-mg-si alloys. Among them, materials such as 6061 and 6063 are the most widely used. Aluminum square tube specifications outer diameter 8mm*8mm-300mm*300mm spot specifications complete
