Is it good to choose a welded joint or a cold-pressed joint for aluminum alloy scaffolding?

Oct 18, 2019

At present, aluminum alloy scaffolding is connected by welding method and cold pressing method. Because users who do not understand the industry feel very headache, especially many online over-promotions, many users do not know how to choose aluminum alloy. Scaffolding, this article analyzes the aluminum alloy scaffolding of which process is selected from the two manufacturing processes of welding and cold pressing.

   The welded aluminum alloy scaffold is connected by welding, and the pipe is connected with the pipe in the form of welding. The butt joint is to connect the pipe with high temperature. The joint strength of the welding has been proved by experiments and practice for many years, and the connecting parts are firm and There is no looseness; the scaffolding made by the cold pressing process uses the pressure of the machine to deform the aluminum alloy pipe and clamps the connecting parts by deformation, so since the tube formed by the force deformation is stuck, the aluminum alloy scaffolding It is a high-altitude product. During high-altitude use, swaying is inevitable. When it is shaken, it will generate forces in all directions. When it is subjected to forces in different directions for a long time, the aluminum profile will also be deformed accordingly. The deformation will produce the looseness of the joints, and the welding joints will be firmly connected even if they are subjected to different directions of force. The forces from different directions will disperse the whole pipe or the whole seat. So it is impossible to produce looseness. As for the argument that other online propaganda welding will destroy the molecular structure, it is a false statement.

    From the history of the development of aluminum scaffolding, both welding and cold pressing have existed. However, due to the average force exerted by the cold pressing and the continuous use of force, the joints of the pipe fittings are prone to loosening, from mechanical experiments and many years. The use of the site to see the cold-press process connected aluminum scaffolding products. On the one hand, due to the phenomenon of looseness, on the other hand, the sales price of the cold press process is usually higher than that of the welded product, so the aluminum alloy scaffold connected by the cold press process has gradually been eliminated by the market in recent years. Most markets choose aluminum scaffolding for welded construction.
