Welding aluminum alloy needs to be prepared, otherwise its corrosion resistance is reduced, and easy to produce pores. The practice of welding aluminium alloy pipes should be thoroughly distinguished from that of welding steel. Tools that have been used for welding steel are strictly prohibited when welding aluminum alloy. Clean the weld area of oxidation film and other impurities, as far as possible with a stainless steel brush or acetone cleaning.
Grinding with grinding wheel is not allowed, because grinding with grinding wheel will only cause the oxide film to fuse on the surface of the welding material, but will not actually remove it. Moreover, if hard grinding wheel is used, impurities in it will enter the weld and lead to thermal cracks. In addition, as A1203 film will be generated and accumulated in a very short time, in order to make the oxide film as little as possible affect the weld, should be immediately after cleaning welding.
The inner surface of galvanized steel pipe of dalian aluminum alloy pipeline is bright and clean, and the self-oxidation layer is corrosion-resistant. Small pressure loss of compressed air, energy saving. Galvanized steel pipe is beautiful and simple. Aluminum alloy is easy to install and quick to plug. Installation costs are low. Aluminum alloy is easy to disassemble, move and modify.
Aluminum alloy pipes and joints are more expensive than galvanized pipes. Aluminum alloy steel tube can not be used as a water pipe, because the aluminum tube is less rigid than galvanized pipe, but very flexible.
Aluminum alloy is light in weight, corrosion resistant and well formed. Aluminum alloy has good heat conduction performance and conductivity. The non-magnetic properties of aluminum alloy make it used in special electrical equipment. Non-toxicity and recyclability of aluminum alloy.
